I also have some other suggestions. While I personally enjoy ENWorld, and have frequented it since Cromagnon man first drew his first cave picture, there are some other very good sites to visit should ENWorld be unavailable due to technical trouble.
www.dragonsfoot.org is a site devoted to earlier editions of D&D, but with a growing 3E section, and a forum wholly devoted to debate between its members as to what the best edition of D&D is!

As a leader of the "ENWorld Invasion" of Dragonsfoot, I highly recommend it, for both stimulating discussion, and for excellent resources for your 1E and classic D&D campaigns!
www.montecook.com is devoted to my second favorite game designer in the whole world, and quite a few ENWorlders visit the site!
Third is a site I'm not supposed to mention FNORD
http://nutkinland.d20boards.net/ FNORD , but is a place for fascinating discussion of RPG's, rants and raves, and run by a really nutty guy, a dead girl, and a vengance bunny.
Finally, if I might mention, long-time community members might well remember the dark ages of the boards (like earlier this year), when the boards own popularity forced Morrus to limit board traffic to 200 simultaneous users -- PERIOD. It was a horrible time, a time of Human sacrifices, dogs and cats living together, and Mass hysteria. But with the move to a rather well-maintained linux box through the help of Adlon of Mortality.net, things got better. WAY better.
KenM -- trust me when I say, that the end product of the board moves will be a good thing - for you and me, for Morrus, and for the long-term health of ENWorld.
