You know what? It just so happens that we don't have a currently active user group in Oklahoma City. I will, however, help you to start one if you want.
The big concentration in your area is probably Tulsa, then OKC, then Perry/Stillwater.
I'd be willing to help you get one started, in the same way that we are getting them started in Cincinnati, Cleveland, and Central Michigan. We're developing a template, or a script of sorts to help walk people through getting these groups going. Siemens will give support, but these events will be run by the users. It's easier than you think. We've got it all outlined.
Drop me a private message and we can get started. In less than 50 days, you could be running your own OKC SE user group.
