I will be at TechEd next week. I am helping out my co-author Will Stott at a Chalk-Talk Session on Monday, June 4 at 4:45p. The session is titled, "Microsoft Visual Studio Team System for Agile Teams".
In addition to this I will be at the "Open Source Software in Enterprise Development" panel discussion at lunch time on Thursday.
I will also be at one of the Microsoft booths at various times (I'll post more details on Sunday). If you questions/comments/complaints about CodePlex please drop by and let me know.
