You know, you can get a free forum that costs $10 a year if you want it to be ad-free for members, and it only makes guests see ads for ANYTHING. Plus, a top level domain is only like $15 a year also, which includes masking so you can redirect to the free url but it still shows as whateverthedomainis.com. I'm just saying, forums are very very very inexpensive nowadays, and I also don't believe for one second that all this ad revenue is necessary.
So unless Rocket is making a retarded decision by having a dedicated 100mbps internet line to his house and hosting the server himself, there is no way in hell it can cost very much to host this site. Sorry, but that's just the plain truth. $120 a year MAXIMUM, and that's being generous. Anything more and he's getting ripped off.
