If you want to do this, you should just go ahead and do it, but I really don't think you should be asking the members here to come to your site or polling them for info. Sounds dangerously close to spamming the forum, and Adam or the other mods might not appreciate it.
Maybe you should PM Adam and ask him if you could help improve this site.
Otherwise, theres LOTS of free domains available on the web. Just pick one that isn't too involved. 50Megs.com has free domains, you just have to let them put their name in your address. Otherwise you have to pay for the domain....I'm pretty sure thats how it works everywhere.
