It's really nice to meet you! Yes, a lot of the members here are former members of BrainTalk, and quite a few still visit both forums. I was a member of BrainTalk for almost three years, but then this site was formed when BT crashed and was off-line for several months. It's so friendly here and I like it so much that I've just never gone back.
I hope you find that you like it here, too, and decide to hang around with us sometimes. You are definitely very welcome. Good luck with your medical problems, and I look forward to getting to know you a little better.
