This is the right place to come, but it's not a huge community, so you won't find games starting every day (I guess I've seen roughly one new game per week advertised here). I guess the games announced here are the longer term games, typically hosting once per day, or less.

There is also sticky on the main Dom3 forum for the IRC channel, and I gather that blitz games are often started off the IRC channel.
