Marco has worked with me on a number of projects and it goes without saying that he brings a lot to the table. Congrats to vB.org on that note.. I don't know Princeton personally but I am sure he will contribute much as well.
Again, a big thanks to Brad and the rest who have contributed their time and efforts. You all will be missed but not forgotten.. (Unless they prune 10 years down the road and we're all gone

)
