Several of the authors here on MSExchange.org are as you already know also Exchange MVPs. MVPs are invited to a yearly MVP summit in Seattle, Redmond.
Below you see a picture of the MSExchange.org authors who attended this years MVP summit. From the left: Shaji Firoz, Nathan Winters, Anderson Patricio, Rui Silva and finally Neil Hobson.
Unfortunately I didn’t have the time to attend the summit this year 🙁
