When you post an item(s) you have to sell, trade, give away, please be as descriptive as possible and state all conditions of the "sale". ie: Free whatchadoodle, slightly used, $5 plus postage. OR 1 brand new thingydoole $15, plus postage...free popstage... etc Also let the buyers know how they can pay you, paypal, check, money order. Remember; A picture is worth a thousand words.
Please remember to thank someone when you get whatever they gave or sold to you.
In donations if you want to give anonymously thats OK. But please communicate through pm's so neither party is left wondering. An anonymous thank you post (out for all to see) can say something like 'thank you my secret garden gnome from XX for the whatsydoodle I've been looking for.' This way everyone isnt asking for a whatsydoodle from the giver.
