I want to connect with people who worked/working with gem5. How do I do it?

I have been doing some research related to reconfigurable architectures at Embedded Systems Lab, University of Florida. I have reached a point where I want to consult with professionals whether the simulations I am running are up to industry standards and valid. One of my friends' told me a small group at ARM works with gem5/McPAT and I wanted to connect with the group so that I can learn more, discuss and validate my experiments. If somebody is active in the discussion board or know someone who is working on a similar project please direct me to them.

Thanks !
