Joined a Microsoft Speakers group : INETA for BizTalk, WCF, AppFabric
I think I’m the only BizTalk developer on there (I had to ask them to add BizTalk as a section). So if you are aspiring to be a speaker and can easily present well thought out presentations on the latest and Greatest, then definitely sign up. We need you onboard! ( I only cover Georgia or South Carolina).
