" the fact that most items are still with the donators, and the fact that I am not sure how they would feel about their items being sold instead of donated would go down with them "
1. why can't the donors send pics , info of item to one designated despot /organiser of auction ?
2. once item is donated, the ownership transferred to the Message Board, it's like you give a dollar to the homeless person, it's none of your freakin' business how the " new owner of the dollar " uses that dollar, yes ? ( at this point I have another excellent political joke/observation but it won't pass censor )
3. Donations are made freely and should have no string attached.......... if they demand " pre-condition ", personally i would tell them to go take a hike.
