We have a new article today from Oleg Tkachenko, one of our MVP's, about indexing XML for faster querying. Go check it out now!
Also, Michael Rys has listed upcoming Sql Server / XML webcasts.
Apologies for the few updates lately. We're all trying to lock down the next Betas of SQL Server 2005 and Visual Studio 2005. Expect things to pick up again in a week or two.
