Must agree with Mischief I had one of the ladies contact me last week who must have picked me up out of the social boards, or else I can't imagine any other way she might have managed to pick me out of all the other lovely people here. We're well on our way to what I'm hoping will be an enjoyable roleplay for the both of us.
As far as the RP request boards go though, I really only look through them once every one or two weeks. It seems most of the time the one's on the first page are pretty uninteresting to me. Which isn't surprising, there are so many different possible interests it's pretty unlikely that I'll just find someone with similar interests at random.
I do intend to use the request boards however, though I plan on just doing a single thread per concept. Since that allows me to draw a more specific audience or interested potential partners to my specific ideas as well as put a good deal of relevant information to the specific game in question down for potentially interested parties.
