I "borrowed"a feature from .Text
Well, displaying a "most active members" strip displaying logins and the number of posts they've submitting in some ordered fashion isn't necessarily a .Text creation per se (you've seen variations throughout the Web for years), but I took note of it when building a community imaging service for my site, and just a couple of days ago wrapped a listing of the top posters within a membership communiy within a user control and dropped it on a page:

My users really love it. :)
