REPOST:
Seems like some people are having issues. Here is a walkthrough:
1: Register here.
2: Go here, and at the bottom, click the icon on the left, which is the 82nd AIRBORNE patch.
3: After that, go here, and then click the box that says Sign me up!
4: Go here and then make a post with the template used by others.
5: Pick one of the first 4 links at this site, whichever is faster.
6: After the previous download is finished, go here and download the map. After installing, extract the contents of the .zip file into "C:\Program Files (x86)\EA GAMES\Battlefield 2\mods\dconx\levels"
7: 13th MEU is in Delta. Sign in to Delta here.
8: You're done! The tournament will take place on Sunday, February 6th at 6 GMT, or 1 EST.\
