I see your point. What I find a bit disrespectful though is when people do post ads for PSLs on a PSL board and get responses asking them to join games. I'm not saying games shouldn't have a voice, but sometimes it goes a bit too far (I can think of one game specifically from about a month or two back), it comes across as a bit disrespectful. Not everyone wants the drama and extras that come with a game.
Everyone deserves a place they can find what they want. That's all I'm trying to say. I think what OP is trying to do is going to be a good thing for everyone involved.
