Display list of recently commented on posts

Dear all,

I searched the Forum and Google but could not find a solution to what I am looking for:

I want to display the last 5 posts that were commented on. Not the last 5 comments, the last 5 posts that people commented on. That way the same post would not show up twice if two people commented on the same post within the last 5 comments.

In addition I’d like to show the name of the commenter and the comment count. I guess that’s the smaller problem, but does anybody know how I can display the last 5 posts that were commented on?

Any help would be highly appreciated.

Thanks a lot,
Martin
