Just an FYI that I will be presenting two sessions on OpsMgr 2007 at MMS this year.  The first is "Targeting on Operations Manager 2007" - session SO25 - and the other is "Monitors, Aggregations, Dependencies, Rollup:  Sorting it All Out" - session SO26.  There MAY also be one on ConfigMgr but it is not cetain yet.  Hope to see a bunch of you there!
