Christophe has posted the links to the October Cumulative Update for Project and Project Server 2007 to his blog. Get it while it's hot!
Also, in case you missed it, Christophe also posted the first sneak peeks at SP2 for Microsoft Project and Project Server 2007. There's not a lot there yet, but he posts a release timeframe between February and April of 2009.
Thanks for sharing, Christophe!
