John,
While I don't believe Dale has ever "written" it into the guidelines for the CR, it has usually been understood (as a courtesy?) any list memebers trying to sell an item, especially one which may be of interest to the Group, usually announces it before going off to eBay.
In the case of your bottom bracket, I found the "ad" a bit crass and certainly didn't care much for ..."if you want it go get it on eBay.." Considering you have a reserve price for this item, it seems strange not to have presented it to the list first!
I'm not interested in a titanium bottom bracket, but we may have some members who would love to have Stronglight's version!?!
Perhaps El Presidente (Dale) would care to comment on this (if any is needed?)?
Thanks,
