I agree about the web site. It's not my school's site but I find it has a lot more information on it about the style. Inside Kung Fu magazine has had a lot of articles on our style recently as well.
We don't do chi sau as extensively as Wing Chun, but we do have several moves that immobilize weapons so we can follow through with attacks.
As for Chin Na it's a large part of our program. Students are required to know lot's of chin na at each level. I also have flow drills for the students so they learn to move from one lock to another and they're required to develop their own drills at the upper ranks.
