If you want to become the Microsoft Office SharePoint Server (MOSS) that you always dreamed to be and you are in the Chicagoland area, then you've got to go the MOSS Camp on November 9th in Chicago. Read my colleague Dave Bost's blog post about it.
My first experience with SharePoint was at my previous company a few years ago and if you saw SharePoint back then you would have been as underwhelmed as I was (performance sucked). When I first saw MOSS 2007 last year (before I joined Microsoft) I was blown away. It looks like the team dealt with the performance issues and added so much more. In fact there's so much under the hood that you need to go to camp to learn about it. So go on over to http://www.mosscamp.net and get ready for your MOSS Safari!
