Seriously cant see why is this is still not available at our forums..
Would save alot of space in market sections, and make them less confusing.
Saves time. Alot of older Sell/buy topics have outdated topic titles, so people just click them to find out that items are already sold/bought
People don't have to make new topic each time they have new item for sale.
Could be 1 or 2 market threads / per user, and not 10's 20's or hundreds as it is now.
Shouldn't be big deal to implement this
