The Trading Section will allow TPB members to post what they are trying to buy or sell. It can be just like the one in the RS Forums where can people tell what they are trading. It will be located as a forum and when people would like to buy or sell something, they make a topic. Then other members may comment on buying or selling something to the author of that topic.
Examples of what people would put as a post:
"Buying 100 chickens"
"Buying 20k rune ess"
"Selling Rune 2H"
People can also add additional information if they would like.
