I for one would like to see a forum specifically for H2H conversation - setting up matches, AARs, trash talk, etc.
I'm a novice player and definitely casual about the whole thing. It would be nice to have an informal place to hook up games with similar players. This main board seems too general for that, and I took one look at Panzerliga and was just like "whatever"... I don't need boring-ass official stats and rules, nor to I wanna play tile-counting mathematicians, just want to have fun a couple hours a week.
If there's a specific place for AARs and such I think we'd see more people writing them up, and a richer (but still casual) H2H community.
