Jim,

In my earlier post I said: "Non-Commercial Logo Usage - Club members are free to use the logo to indicate their membership in the Club. This would allow the logo to be used on web sites, stationary, business cards and the like. As long as the use is non-commercial and it clearly indicates membership status. An allowed exception would be the use of the Club Logo on a Club member's trade or sale list."

I think that the use of the club logo in eBay sales is a good idea for promoting the club. It falls under the exception I mentioned previously. The use of the logo must indicate the membership status of the seller. For buyers, there is an added benefit of seeing the club logo on an eBay auciton, because the buyer will know that the transaction is covered by the Club's Code of Ethics.
