You mean have him try to sell it for you? You dont have access to the PM system either till 40 posts. So you couldnt even have contact with the people trying to sell it you would have to do it all via email.
Plus using his account (Username and password) is highly frowned upon. Would basically be like having multiple accounts which we dont allow.
I will contact Trotter for you and have him send you a PM with the answer. Since he is a Admin he can send you PM's.
