Thanks Maerland,
Every once in awhile I post something along that line.
NEW PEOPLE....
the same person CAN host, and administrate, a dominions game. If you want to do that, great.
OR those can be separate. There are options for a game hosting on LLamaserver.net (play by email games) or Dom3Minions.com (direct connect, plays like a solo game but can include multiple players). The administrating part includes some things like creating a thread here about the game to announce it, get people to join, settle disputes, contact the server hosting the game if you want changes such as setting someone AI or changing the hosting times.
