I know the game is old school but it serves well for those that don't have a lot of graphics power.
I made an effort to get this up and running. I was playing single player for a bit but my co-workers talked me into getting it into multiplayer mode.
We are meeting on Fridays @ 7:00-8:00pm MST
If you have the game and are interested in playing along, dust it off. We use a bunch of custom maps and TeamSpeak for communications. All the files are in a .zip archive to save file searching and downloading in the game.
Here's the link to the web site with all the stuff needed to get going.

If you would like to join in, you can still get the game here http://www.gamespot.com/pc/action/callofduty/index.html . On the right side you will see a link for the "Digital Purchase"
Hope to see any and all!
