We don't have any Telerik-specific user groups that we know of, but I'd love to point you to two Chicago-area .NET user groups which you may not know of: the Chicago .NET User Group
and the Chicago Alt.NET group
Please feel free to contact me directly if you have any other questions.

Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
