Hello, i didn't find any guide about this here, so i'll give it a go!
Do you have some spare gold? Do you need more gametime? Sell your gold to MMOInn and get timecards for it.
So, here's how you do :
Go on MMOinn Procurement - Barter Exchange for Supplier of Gold, Selling Gold, World of Warcraft Gold, FFXI Gil, Final Fantasy XI Gil, Lineage 2 Adena -- wow gold,wow of warcraft gold and choose EU/US. Then pick server and faction from the drop-down menues.
After you have picked the faction and server you have your gold on, you write your character name and how much gold you want in the spots just below. Then press Supply invoice.
Then you get a screen which will refresh each 4:th minute. After they have confiremed it, you press invoice button on the left of the order picture. Then log on the server and character on WoW which you have chosen. They will list a character name and how much gold they want on thé order.
Go on wow, take a picture just before you send the mail with the gold to the character they supplied, when it says : you sure you want to send XXX gold to XXX. Save it as a jpg file and it must be under 300 kbs. Then take a picture when you have sent it, Just when it says Mail sent.
On both pictures, you must have your backpack open, so they see how much gold you've got. Press confirm, and a screenshot window will open. In the first bar, browse and pick the picture which was before you sent, and the second bar the picture after you sent. Press confirm, and a window will say that you have supplied them. Then wait for the money you sold it for to come into your MMOInn account, on the credit balance.
This makes so you don't need a paypal to buy gold/pl/cd keys from their site. you can be underaged or overaged! Post here if you got questions!
MMOInn Rocks!
