Как ограничить количество социальных групп, отображаемых в профиле?

Возможно поможет:

Neither of those is the query. Look for the query just before the "// Display groups the current user is in" line. It's called "$mygroups" and that is the query you would have to modify if you want it to only spit out a certain number of groups (add "LIMIT x" to it).
