Hi ,all I have a question. I want to produce groups of blogs, eg. there are some users that have their own moderator and their own front page. Moderators of the group can manager and promote nodes from only his group members and their front page can be gained only via their own domain. http://domain.com -> one group http://domain2.com -> other group

That's looks like OG approach, but it does not exactly the same thing. I'm sure that there is such module (e.g. taxonomy access) that can be used for such thing.
