This is a list of Diplomacy material on the net. If you think you know of other sites which I should add, please email me.
Eternal Sunshine - My resurrected Diplomacy zine, with games and other personal foolishness.
The Abyssinian Prince - The late Jim Burgess published this awesome PBM zine. Here are tons of back issues (which I haven't added to the Archives yet).

Diplomaticcorp.com - A play-by-email community. Always a standard game and many variants to join.
Dipwiki.com - A growing Diplomacy Wikipedia, with a terrific variant section too.
Diplomatic Corps - Lots of links and information. Hasn't been updated in a few months at least though.
Windy City Weasels - Web site for the Chicago-area Diplomacy group, which is VERY active, probably one of the most active in the entire U.S.
