Buck posted a howto on shelving from the command line. For those of you out there with the December CTP, you have a chance to get an early look at how one of my favorite features in Team Foundation Version Control. It's also one of the areas I'm responsible for testing, so I'm both excited to see it getting 'face time' with you guys, and anxious to see how well it's holding up so far.
If you get a chance, definitely give the feature area a spin and tell us what you like or don't like about it, and especially any bugs or unexpected behavior you encounter. The newsgroup is (still) a good place to discuss Team System, but feel free to send any feedback my way, as well.
