Anybody here use GtkRadiant?

For those of you who don't know what it is, GtkRadiant is a popular map making utility for a number of FPS games. I'm curious if anybody else does any map making of their own.

Also, I'm looking for a good user community to post questions, ask for feedback, yada yada. I tried googling but didn't really find anything worthwhile.

Me thinks someone is trying to boost their post count.
