Ben is one of the FRUA greats. He has made s couple modules that out-Gold-Box the Gold Box games. You can check out his insights in the various UANLs in the aptly named "Gold Box Corner". He had retired from FRUA for a while, but seems to be back in a big way.

When he's not FRUAing, he run a PW (Persistent World) for Neverwinter Nights 2 (I think it's 2, it might be 1).
I don't think he'll do anything for DC, not until we've reached version 1.0 that is. But, he is supportive of DC.
