Shadow,
Create a journal entry. That will create a page for everyone to talk programming. Grab the address from that page, then edit the Programmers Haven page adding a link to the actual Haven. The first page you created kind of acts as a gate, or a splash page. Does that make sense?
As for recruiting help, I personally like the idea. What's not to like? There is that pesky advertising issue. I would talk to someone in the meta forum because I wouldn't know where else to turn.
