Now that this thread has gotten necroed, I'm not sure if I told you guys that the Nunnery was a thread where minors and adults were both allowed that sometimes escalated to borderline cybersex. Since the thread was pulled by Google last year I unfortunately have no caps. I dunno if any underage users and adults ever cybered with each other in the actual thread, but I certainly wouldn't be surprised considering here were many "romantic relationships" on the forum of that type. It was definitely at the very least very, very skeevy.
That's all I have really to say on TV Tropes right now. The site is under new management, but I haven't noticed it making any improvement in the quality of the trope pages or the forums.
