I've hopped on a few times in hopes of finding a game, but haven't had much luck meeting anyone! I'm using 3.0. Is this the correct version of the mod and just no one's on or am I using an outdated version while everyone's using the new one?
You're using the correct one. It's still just very new and there are only so many people that have it. Your best bet for the time being is to just set up a time with people via this thread or on the Vassal section of afewmaneuvers.yuku.com. Try being on around 10:30 Central this morning. If you don't see anyone on right away, don't worry, it won't be long.
