Powerful multitool

Posted on 30 November 2021
It does all a community platform would do even without its extensions. I have used almost all the extensions and I can say they are powerful
Ease of use
Although it gave me the impression that it wouldn't be easy, I was wrong. I just had to spend a little time to understand how easy it is.
One of a kind! The guys in support are very good, polite and always to the point! Reply to requests within 1 day and sometimes immediately.
Everything I have looked for so far, is there. In forums they always provide examples and links to the documentation in order to help users.
I used this to: Developing websites for public communities and private companies that implement user profiles for their employees, customers, suppliers, etc. CB and CBsubs are powerful tools. CB exists for many years because it does things properly. Keep up the good work!

Suburb Support

Posted on 18 October 2021
CB has a wide variety of add ons that make it a great product. In addition to saving time for the users, updating is easy.
Ease of use
Very user friendly even for novice users. We have been using this extension for over ten years and are always finding something new.
The support has always be top notch. They got us out of a real bind when we upgraded templates. Thanks Nant!
Very well designed and easy to use. It contains many examples that translate into real world scenarios. Love the idea of a PDF
I used this to: Our site uses the CB to keep track of users, their cars and to allow other users to email easily. We are working on adding a gallery for photos and other images.
It works well and has more features than most users will need but there is something for everyone.
Ease of use
Easy to use. Quite intuitive and quickly becomes second-nature tor routine operations. Very transparent to the front end.
In addition to an extensive forum there is personal excellent and fast response to questions not covered in the forum.
Very well documented. PDF documentation with many screenshots - almost too much is that is possible.
I used this to: Non-profit group record keeping and interaction. CB allows users to maintain their own records.

Superb Support

Posted on 29 December 2020
Community Builder (CB) is by far the most robust and comprehensive user management system available for Joomla.
Ease of use
While basic uses are very intuitive, more complex uses definitely require reading the documentation or reviewing guidance in the Forums
If your have a paid support level, like Professional or Developer, the support of the forums is excellent. Top notch.
The documentation and video tutorials are extensive and comprehensive. The user forums are an additional source of information.
I used this to: Managing wed site user bases on several web sites. It is my "go to" tool for managing any web site user community.
The number of things you can do with this is only limited by your imagination. It's a beast of an extension with so many tools.
Ease of use
It's pretty straight forward for a web/tech-savvy person. The more functionality you need the more configuration you have to do.
Support is also where this shines. They go well above and beyond to help you. I set up an extremely complex system and they were great.
Lots and lots of documentation with videos and a huge forum. Nothing missing here.
I used this to: I set up a complex registration form for an environmental group to collect memberships to protect birds. I exceeded my client's expectations and has worked great for 3 years. You can do just about anything with it related to users and collecting information or more. Superb tool!

Excellent support

Posted on 14 December 2020
Excellent functionality. Does everything I need to run a subscription community.
Ease of use
Excellent ease of use. As a non-coder, I have been able to install and maintain Joomlapolis.
Recently had a significant upgrading issue. Support staff was dynamite and helped diagnose and fix the problem.
Excellent online and PDF documentation along with video tutorials. The presenter can be a little dry at times.
I used this to: Been running our site for 5 years on this including CB, CB Paid subs, and Group Jive.
With tons of functionality, I've been able to turn any idea into a reality. Developers will love it.
Ease of use
Easy to set up, but you need a good understanding and maybe developer skills in order to be able to use the full range of functionality.
The support is really amazing. You are never left out in the rain. Comprehensible questions are answered comprehensibly.
Very good and extensive. Only for very special functions, e.g. Auto Actions, etc., I would like more use cases and bit simpler explanations.
I used this to: I've been using it for over 10 years for a larger Camper Travel Website and Community.
CB makes Joomla to turn into a real pro-instrument to work with users. Able to achieve any goal. From a simple blog to a huge web portal.
Ease of use
Need time for understanding. Hard for normal users. But when you get hit, you can create everything you want. Very many variants for use.
Very fast support. Answers instantly. Some times i think i talk with unhuman minds =)
Everything is in place. In the docs and active forum you can find a lot of interesting things that can help you with your needs.
I used this to: I used it for sites, where need some more specific functionality for users like:
1. Educational site.
2. Blogs.
3. News portal.
4. Corporate website.
On word. Amazing. Such a powerful tool with what feels like limitless possibilities. If you can think of a function, its there.
Ease of use
For a plugin of this size it is very easy to use, and surprisingly fast when you consider the amount of what it can do.
FAN-TASTIC. Worth paying for membership for this reason alone. Phenomenal support through regularly monitored forums. Excellent.
This is your goto research for this package. All the documentation for CB and all plugins is available and very in-depth, perfect.
I used this to: A large community based website with different tiered levels of membership all at different price brackets. Content specific for each tier with buttons working different functions based upon them. A huge networking tool.

it is good

Posted on 16 May 2020
it is very powerful, specially CB Auto Action is very useful. don't use CB without auto action :)
also you need to understand, you can not
Ease of use
more config is easy, but you may want set profile field access to registered only
if you subscribe, they have a good support but not in the deep coding.
more of document is old or deprecated and some of features has not any document and you must ask Kyle in their forums.
I used this to: used in my community, i used it's webservice to create user in joomla.
