indeed, boxtops, I have just looked at the record of ATOB2, who was a member for one day when AB started in 2000; ABers like andy-hughes busied themselves asking each other random questions to try to drum up interest. He asked 159 in a day, one of which got 10 answers, the rest less.
For his one day's work he's got a 5-year membership badge and a marathon starter badge.
Curious.
