We have a Half-Life Deathmatch server!
Address: twhl.oskar-lh.name
The server is located in Sweden and has been tested by Joe, Dim and Atom and game play is smooth in Europe and eastern United States. It currently runs a few of TWHL's highest rated maps. If you want a map to be on the server, write and I'll install it. Later on I'll create a web page where you can pick any HLDM map from TWHL and the server will automatically install that map. If you want admin privileges, send me your Steam ID (join a game server, write status in console, it should look like this: STEAM_0:1:23456789).
