Right, don't have any specific sites for you to visit; I can only recommend using Google to find forums and advertise on (signature link if necessary).
I never got around to the last one; I'll give it a quick look over later and see if it's worth bothering with, then I'll get back to you. I suppose you could Google a few forums and have a look to see if any of them are worth a shot.
Thanks for asking dude!
