My roommate and I, as well as anyone else who happens to be on, try to group up regularly as we beta test various dungeons over at Project 1999. We have really enjoyed playing on this server over the last few months, but I would like to raise awareness. The server is currently pure classic (with future plans involving only Kunark and Velious). If you want to roll up a character and hunt around on here with us, we are taking a different dungeon each weeknight.
Here is the official post regarding what dungeon we are hunting in on any given night; this will be updated periodically, especially as levels are gained and we have the desire to hit other places.
Here are the main forums themselves; browse around, sign up if you want!
