For any of the CC games that run with DX7 or earlier, there is a place to play online (similar to the old MSN Gaming Zone) at www.ewarzone.com . Click on my banner below for a link.
I'm new here, so I don't know where you play multi-player games. But if you don't have a regular site to play at, you should check out the eWarZone. Membership is free and there are no ads.
Once you log into WarZone, you would want to enter the "Other Games" room. Anyone requiring help can contact the room administrators Golden Knight and Adnak1.
