case in point that these message boards don't get enough attention -
First, allow me to welcome you to DiplomaticCorp, albeit belatedly, and suggest that you monitor the webpage often, particularly the "Open Games" option at the top of the page. Selecting that link will take you to a listing of the games that are currently open and looking for players. Selecting Join this game! there will trigger the email process between the GM and yourself. The GM of the game will typically explain everything else you need to know (other players, deadlines, maps, etc.)
Once you have a game going, browse the site for all the cool gee whiz features like the statistics, DipWiki, variant listings, and of course the rankings.
It's also a very good idea to have an adjudicator program (I suggest Realpolitik) on your computer for use in games. Google "Realpolitik Sourceforge" and you should be able to download the most recent version.
Aside from that, I would also invite you to join the Facebook page for the group (search for Diplomaticcorp).
If you're still looking for a game, and open to variants, I have open slots in my game of Sengoku available right now...jump on in, as long as you're willing to commit to playing the game through to completion.
