Filter or Block Groups from view in user cp
 

Would be nice if there was a way for users to filter Groups from their view on the Groups Index. For example if there are Groups they know they never like and will never want to join, and just don't want the names of those Groups cluttering up and extending the length they have to scroll when looking at the Groups Index, it would be cool if they could 'block' those Groups from their user cp

I would say it should be better to wait for the next version of vBulletin as the social groups have just been created, as such it's safe to assume that more functionality will be added in the next version, including things such as sorting and categorizing.
