I personally like seeing the names of the people responsible for that map.
Having their name on the map is fine but to include everyone, I would think a credits page would be best. One that loads a XML file that we update with each release or something maybe.
I agree Tony, adding that room would be a hassle seeing how most people never even go in there but I thought I should post it just in case. I tested it without it being mapped and I being in the room and all that happens is that the arror goes off the beaten path. No biggie.
I am part way through doing the /loc of special places and things in Wailing Caves. Just waiting on a spawn so that I can get the exact name.
