I know zilch about Boardreader other than that Chowhound data appears there. Though, happily, I am not one of the current "top authors" (being a "power user" is enough pressure! :^} ), my avatar appears above that list, under the Site Members heading, but misidentified as belonging to Joe Babbitt. I looked at a few of the other avatars, which do match their user names.
Anyone know how/why those particular avatars appear on Boardreader? How often they change?
