he was also know as:
boudreaux-cyclingforums.com
bikerbilly-forums.bicycling.com
bubba-serotta.com/forum
and possibly others, might want to add this--bikeforums wasn't his only hangout
you don't even have to list his haunts, just put something like "known by various names, sydney/bourdeaux/bikerbilly/bubba among others, he participated on various forums--tallying up nearly 50,000 posts, all in the service of fellow cyclists"
somethin' like that
good letter
