Halo 2 Multiplayer Inaccessible

Apologies to those who tried logging into Halo 2 for Tuesday's clan night. They have apparently updated the matchmaking playlists to require several map packs. However, those map packs are not accessible for download from within Halo 2 anymore. I will look into solutions to this problem, but for now H2 multiplayer is not available. I also forgot that Xbox Live Party chat is not available for original Xbox games due to their limited Xbox Live support.
