Mikki, go to the Classified section and at the beginning there are listed rules for selling and such.
If that doesnt answer all your questions, just PM Patrice...she is very helpful.
(I am not sure what it spells out about Paypal, but I think Patrice is saying that paypal needs to be used in an "honest" way, and board members are not to try and manipulate that system.)
I apologize in advance to her, if I have misinterpreted.
