I have been reading this one for a while but forgot to post it. Great insight into Microsoft's Record Management practices. BTW, for those who do not know, the next version of SharePoint will have records management features built into it.

Rumor has it that the next Beta for Office 2007 will be released sometime next week. I cannot wait!
Microsoft has launched a new area of its "Future Versions" that lists Office 2007 information geared towards developers. Well worth a look.

and select which role bests suits you.
