After couple of years of debates to do this or not, we have decided to move forward with this group. There is no similar group like this in Chicagoland area. We have done topics with the Chicago Windows User Group in the past and will continue to support them in joint events. However, the membership for a Windows user group vs. a System Center, EMS, datacenter and client management, is much different.
If you are in the Chicago area, please sign up.
The group is co-founded by Rich Lilly. Check out his blog here and follow him on Twitter
