It's been around a while, just wanting to advertise it again for those who may not have heard of it. The link has a list of rules, which are pretty simple. Such as you need to be a guy, and actually in costume on your site. ^^; Exclusions are made for pages paying homage to guys in costumes. (IE Cos-men).
Even if you're not a guy, don't have a website, or whatever! Feel free to go look at the guys' sites that are already signed up! That's another benefit.. extra traffic, more people seeing your pics! =3
