I had he same worry.
Im usually careful and lace all my comments with things like "I think" or "in my opinion". One of the few gaurantees Ive ever felt pretty safe in making is that IF you can get thru the demo for Dom2 then it will live on your machine far longer than games of equal cost. There are people here who have played Dominions for years and still debate tactics.
There is a web site up for games. Its been a project in work. Its working pretty well now and I suspect someone else will put one up soon.
There are also games arranged here, and in IRC. Id say its fairly easy. As soon as there are enough that want a game, they usually start one.
