If you have items you would like to trade for something else just post in the guilds forum what your item is. If someone has an item posted that you like, quote them and tell them the item ud like to trade them. simple and easy right? Best part! you don't even have to trade! you can just join to chat with ppl and have fun! after all ppl to chat at trading posts.
have fun kiddies!
sincerely your guild master!
