Some time after we had worked in this manner, we accidentally came upon a name for ourselves. I had, at some point, placed photos of us on a board, with our role initials under the pics- it spelled "PO", "TL", "AC".
It sounded like something pronounceable, and when Ingrid realised that Potlac can be pronounced Potluck, the name fastened itself and never came off.
As you might or might not know, a potluck is a meal to which everyone brings their own food for sharing with the others. A successful potluck requires some sort of coordination between the people who come to the meal, otherwise one will have all dessert and no mains.
