First off:
I'M BACK!
Back on topic:
We need to fix the Source Ports section on the info page. Skulltag (which I recommended for playing DOOM online) has been discontinued, so I need to replace it with its successor, Zandronum.
Zandronum
A port that allows you to play DOOM online with people around the world:

I also wanna throw in three other source ports:
ZDOOM
The granddaddy of all DOOM source ports:
http://zdoom.org/News
DOOMsday (a.k.a. JDOOM)
Like Risen3D, but has multiplayer and support for more graphic and audio mods:
http://dengine.net/
ZDaemon
Another online version of DOOM in case you don't like Zandronum:
http://www.zdaemon.org/
How soon do you think the section can be updated?
