I added support for Doomsday multiplayer to Doom Explorer
- you can view server list, connect to server, start you own servers etc.
There is a problem with the PWAD names sent by the server - not always correct, especially if the characters '_' or '-' are present (for example sigil_compat.wad). In this case, you can try to join the server from the Doomsday UI.
I hope it will be corrected in next versions.
