how can I make my server be a .com instead of my ip address?
Once you have a .com name, you just need to find a way to tell the name servers to point towards your IP. I own nitramtj.com through dreamhost, from there I point my name servers to afraid.org's servers. afraid.org lets you then choose where the name points to, and also lets you manage the subdomains. Just make sure you make your domain private so others can't use it.
But yea, that's half the reason I started my server, so people wouldn't have to remember an IP.
Oh I also saw 3 of you guys were in the server, did you all just leave, or were you randomly disconnected?
