Ben was one of the first members of the Subversion team, along with Karl Fogel and Jim Blandy.
I’d like to wish Ben good luck in his new opportunity and give him a personal thanks for the work he’s done to bring the Subversion product to the point it is today. The product and community would not be where it they are today without his work — both in the code itself and the work he did in the community providing support (and even an occasional Python script) to help us out during our Subversion implemention.
Good luck Ben and thanks for all of your contributions to a great product!
