Just to let people know, Doom3World isn't down and out, just down temporally:
Doom3World ain't dead!
Here's the e-mail I recived from it's webmaster:
I'm glad you email me. Been waiting for someone to approach me. The server got compromised, abused for a DOS attack and taken offline by the hosting company. I hope I'll be able to obtain all D3W files back early next week so they can run a fresh install with hardened security. You may want to spread the word about it. All user passwords were stored encrypted. Just in case it's always good to change them after a server breach.
