I will start off by saying I do not recommend buying and selling accounts in case you get scammed. I, or any of the staff at Rune Glory are not responsible for any lost accounts.
That being said, here is the format you should be using when selling accounts.
YOU MUST HAVE PICTURES OF THE FOLLOWING!
1. Combat level
2. If the account has Recoveries or a Bank PIN
3. Stats
4. Quests
5. Login Screen
6. Bank
7. Black Marks
