I am happy to say that around 7 or 8 september my article on Team System Source Control will be published.
Peoply who subscribe to the Beta Experience newsletter (www.microsoft.com/betaexperience) will be first to get it, so if you didn't subscribe, now is your chance :)
The article is about 30 pages long, half theory, half hands-on for those of you who like to get their hands dirty. In it I talk about features like multiple checkout, branching and merging, shelving and so on.
