Every now and then I pen a few words for the most excellent fortnightly (=biweekly) UK MSDN Flash Newsletter. Given I have been spending a lot of time recently talking to developers and architects about building on Office as a platform, I thought the MSDN Flash Newsletter would be the way to spread the word. The only problem - to say it all in less than 500 word. Well, 3 revisions later, and some additional editing from The Moth, here it is - http://www.microsoft.com/uk/msdn/flash/20071017.htm
And, if you don't get UK MSDN Flash Newsletter then sign up today - it's a great way to keep up with what's happening.
