req: fave forums (sorted by # posts in each forum)

[supreemball]

i'd like a 'favorite forums' hack which would be sorted by the # of users' posts in each forum..

this would show up on forumhome, and would maybe show 3 max 'favorite forums' if the user has posted more than, say, 10 posts in each forum..

say i like to post in 'games', 'misc', and 'entertainment' forums.. those forums would show up at the top of forumhome in a category labelled 'Your Favorite Forums", before all the other forums, for quicker access.

i know a hack like this has been requested before, but this would automatically be sorted by how many posts the user has in each forum.

thanks
