and today is 18 and still cant buy gold on trade

from what i have read in older posts, your account donation rank needs to be 'premium' to use the trade feature. So if it's 'regular' now i think you cant buy or sell items through trade. However, i am not sure how much you need to donate exactly. If you find out more pls let me know, i am looking to use the trade feature as well :)
