The Command & Conquer community has launched a server to keep multiplayer going in a number of C&C games that had been abandoned by GameSpy Technologies, who once provided multiplayer services for the popular PC real-time strategy games. According to this Eurogamer report, users interested in playing online can visit C&C: Online, register with Revora and install a launcher which emulates GameSpy servers. The server support several C&C games including Generals, Zero Hour, C&C3, Kane's Wrath and Red Alert 3.
The service has been designed to be a fairly seamless continuation of the online service that was available before GameSpy (Glu) decided to turn out the lights.
A video guide showing those interested how to use the software and server can be found to your left.
