There is an awesome community here! I am a part of the non-profit Techlahoma Foundation ( http://techlahoma.org/ ), and we support local user groups and community meetings in general in the state. We maintain a list of them here: http://us.techlahoma.org/groups
We also maintain a meeting announcement mailing list for OKC.js (our largest group, 50-60+ people each meeting) here: http://okcjs.com/ (click on "Sign Up!" in the navbar).
