GatorDeb took a leave of absense. I think she mentioned that she will be on from time to time, but for the most part is moving on. That's all I know anyways. She made a farewell thread I believe.
Candy and Gator left TA awhile ago (although I think they still visit every now and then)....not sure about DonBurns though. I've noticed a bunch of the regulars have been more quiet than usual.
Some guys have gradually disappeared and you don't know 'til you're browsing one day and you suddenly notice it. Like Brewstermax, where is Brewcy?
In response to the op, I liked DonBurns99, I considered him a "Polite Voice of Reason" in a post-EDNG forum.
Brew.......... Brew is sorta gone. He had a affair with iPTF and has stayed with her. I guess eventually he'll come for a one night stand. Bad brew
Tru dat. He was like a double edge sword though. He threw grenades at newbies who made a bad post (not searching). While it cleaned up TA, it also made people scared to come back. Heck, he's still like that.
