Chances are you will receive a negative feedback and lose the item

If you share your Guild Wars account, notify your account partner of your bids, and make arrangements for them to pick global agenda gold up the item for you if they are contacted in game.

If a buyer/seller is making polite contact after an auction has been won and gets told 'it wasn't me, it was my brother, you'll have to talk to him," chances are you will receive a negative feedback and lose the item/sale.

Another option to this is send the seller an auction pm or email, explaining the situation and telling them specifically which IGNs are yours.

If you have multiple Guild Wars accounts the first choice is to list one name from each account in your auction account profile. If you choose not to do this, then I recommend you do not use any account other than the one registered in GWG Auctions to contact buyers/sellers or conduct trades.

Many sellers/buyers are careful about only trading with the legitimate account holder to prevent cases of fraud, scams, or abuse.

Once a trade has been completed, be prompt about leaving appropriate feedback. If you are the seller, make sure you mark the item Paid - Posted/sent in the options field.

Your feedback will influence other buyer/sellers in how they interact with this person, so be fair and responsible.
