Honestly, this group is one of the most friendly/welcoming groups I've ever gamed with. If we don't recognize you (even if you're not holding models), someone will probably ask you if you want a game, or at least ask what faction(s) you're playing.
If you have a specific point level/list/scenario you want to play, it shouldn't be too hard to find a match. Like cowboy said, most of us can play anywhere from battlebox up to 100 points. On the other hand, if you want to get something real specific, or just make sure you have a match when you show up, just make a thread in this forum. If I'm looking for a certain point level or prepping for something specific, I just make a post and can usually find someone to play.
Glad to have another member in our group! And my wife will be really happy to hear that there's another female player coming!
