Hi!
It's a very good extension!
Have I got to updates if I'll to buy it?
If what you mean is if you will receive free updates, the answer is yes. However, only for the 1.0.x versions of Joomla. If I have to do major work to make it compatible with Joomla 1.5, users who buy now will pay a reduced fee (yet to be determined) to get the new version.
I'ld like to use with the Alpha Content. Is this possible?
Like Lionel said, Alpha Content just organizes existing Joomla content and jReviews also works with Joomla content so you just need to add the content categories you want to have reviews for and that's it. Not sure if that is the functionality you are looking for.
I see the Community Builder support. I'ld like to see list about user's rating and comments at the user's profil in the CB. Is this possible?
I will develop a plugin for CB soon, once some of the issues being reported to me are solved and we have a more stable version. The CB plugin as well as any modules (top rated, latest reviews, etc) will be freely available.
