Yep, I support that.
If you want a specific item it is most often hard to find somebody who exactly wants that. But if there are a lot of offers available you can do a few crosstrades to get the item which you want. I had sometimes trading chaines of 4 trades to get what I want. That was very efficient.
It's impossible to organize such trading chains with messages in the trading forum.
If the people cannot offer a lot of possible trades the amount of possibilites decrease dramatically.
And the best... I need trading partners in a chain of trades. If I have a trading chain of 4 trades there are 5 happy traders involved. I get what I want, but the other involved traders also get what they want.
So... please increase the maximum amount of possible offers!
