Good morning Maxine--I'm not sure there's an active study group going right at the moment...check with Krish on CCIE-DC Study Group. There's a lot of location diversity amongst CCIE DC studiers, so that makes for a challenge. However, I am also studying for the CCIE DC, and I am fairly regularly here. If you have an questions, I'm happy to try and answer.
Best of luck on your studies, MM
