i dont have the yellow belt achievement and im 2nd dan.

also, how do i sell items i dont want?

1st question: The achievments are on beta testing now, and some of them not working yet

2nd question: like all the items. Also, explain that a little more >:|

Ok well the 2nd question is asnwered as so

To sell you unwanted items Create a shop, You can do this by clicking on market, Than click create shop. After you fill out the asked for questions (name, description etc.,).
Then press add item, Find the item click the item, And mark price

Or just make a thread in Items, make a list of the items you want selling along with prices and wait for buyers.

ok thanks guys
