I think the comdel.net domain name is in the process of expiring. I could no longer access it from home. I added the IP address (66.179.84.104) to my HOSTS file and then was able to get back in, but I expect soon that nobody will be able to get in unless this problem is resolved. If people want to try to continue using these forums, see the gamedev.sf.net homepage where I will post instructions on how to continue accessing these forums or suggest a temporary alternative until I figure out what's going on.
