It seems that the information on "running" a blitz game on my servers has faded, or maybe exists only in the Dominions IRC channel. So here is some info on it.
A blitz game has multiple definitions. A game small enough to finish in less than a month.
And also a game where everyone tries to do many turns in the same day or weekend. My server can support both.
I try to keep open blitzes available regularly. If you check
http://game.dom3minions.com/bin/blitz_chk.cgi
you will see them. But I just host them. I do not "run" them. If you want to run a blitz then just pick one and round up players. Let me know of any changes (stops, starts, changing hosting times, making palyers AI, etc)
