Terry,
Yeah, the problem is that a lot of links (such as the link to REP from the main menu) point back to the server name rather than IP address, so the IP alone doesn't work in a lot of cases. GRR... like I say, server configurations are just getting more and more complicated.
You may still be able to get into REP using
http://recforums/64.73.50.193 ... it resolves fine for me, but I haven't been having the DNS problem so I can't verify whether it would work for you.
But yeah the problem will most likely go away eventually.
