It tends to require posting regularly.
But if I don't know you exist, I'm probably not going to PM you.I'm not discounting what you said, I'm just saying I don't see why one thing should have anything to do with the other. Maybe I'm only here to find a woman to tickle. Getting involved in discussions on the board is not relevant to my objective. Some will probably say "it lets the women get to know you better, feel more comfortable with you, etc" Well get to know me then. PM me and we'll talk about what's relevant. I shouldn't have to pretend I have interests that I don't.
