The "unofficial" FT definition of a DO is a gathering of 12 or more board members, wherever, whenever.

The first (apparently) FT get-together was proposed/planned by FTer Catman. Someone added the "do" to make it "Catman Do", as in Kathmandu, Nepal.
Nothing apparently about it. IT was not proposed. It was planned by me. It was organized by me in NYC. I added "DO" because I thought it sounded clever and cute.
There were three Catman DO's in NYC, the third one with 84 FLyertalkers. OTher Flyertalkers simply picked up on the trend.
