I have been participating less in each forum respectively as my career has taken off, I of course still lurk in the shadows for any of you ne'er-do-wellers that might be about. But for me tmf is about the chat, and theater for everything else.
I like the TMF's "true tickling stories" forum, and I visit that a few times a year, but other than that, just TT for me. It's the first one I found, and I just got used to it over time.
