If you could not attend Tech·Ed 2006 in person, there are still a variety of ways for you to participate or access content.  See http://www.microsoft.com/events/teched2006/default.mspx for details.

Also, I am posting my two slide decks here for anyone who wants them.  The sessions are Exchange Server 2003 Clustering Best Practices and Exchange Server 2003 Tips, Tricks and Shortcuts, and you can get them at:
