Johnny, TTT or "To the Top" means just that. When someone has a thread they want to keep in the list of "new threads" but don't have anything new to add, they will type ttt and post it. You will see this a lot more over on BFC when guys are trying to sell something.
Since I didn't have any info for you, I simply put "TTT" to keep it at the top of our extremely busy message board.
(It might have gotten swept to the second page in a year or two if I hadn't acted quickly. )
