One group of particular interest to people here might be http://www.a2newtech.org/ (monthly meetups with presentations of new startups and startup ideas).
BTW, I am in Bham too.
And in May, don't miss http://leanstartupmi.com with Eric Ries, Dan Martell, Brant Cooper, and a bunch of Valley/Michigan investors and founders (including 2 YC companies) presenting. It's going to rock!
Micah Baldwin (Graphicly) & Noah Kagan (AppSumo) will be speaking there...
