likely spam... that sort of thing with the dating seem to come in waves. Used to see that often on the one forum I'm a member of. Not as much now- much quieter.
Reba, I've been wondering this too. It seemed like a bunch started at the same time. I don't trust anyone with a low post count. If they didn't stick around to read and post at least 20 or so times, I just assume they're spam.
