I have been using CB (Community Builder) for a few years with personal websites as well as those of clients. I have never been more pleased with a script than I have been with CB. So many people have it that getting answers to questions has never been an issue. The one time I decided to experiment with something else was a big waste of time. I purchased Azrul's JomSocial and wow was that A BIG MISTAKE (Lack of support, and non-removal of developer's links/brand marks,etc). It's worth it to purchase a CBuilder license, considering the many extensions and integration. From what I have seen in the past 2 years, CB has only gotten better with no signs of stopping! Keep up the good work folks at CB.
