I've been here for six years now, so not all that new, but not all that old. Interestingly, I was on HC, but more late 90's to early 00's. I recall a software change on it (2003?) where I got less active. That was right when I was in the midst of having babies around the house, and had stopped playing anything more than local bars or church services (hate the music, but got to be on stage with the wife, so positive overall there). I wasn't there for the great exodus. I was more active on the Jackson-Charvel Forum throughout most of that time, though again it was scaling down early on.
Anyhow, nice that the forum has some new blood. I like this place. It seems like forums are dying lots of places, but the newer media has things I don't like, just in presentation.
Yes, I'm on TGP too and don't mind participating over there, especially on the rack subforum and amp forum, a bit. I've never run into issues. It's just more stuff to sift through to get to things I'm interested in than this place.
