WHAT TO POST IN HERE:
-Okay, obviously, you can sell your item(s) here. Don't worry, this'll be one of my more checked up upon sub-forums so I can see if anyone is selling.
-You can post quest threads, to note progress or donations to the item or amount of gold you're questing for.
-You can also post charities or giveaway threads, where you offer to giveaway items to the first poster, most often poster, etc.
-You can post wanted threads, in which you ask other members to sell you the item you want for a discount, or full price.

Follow ToS, of course.
