I have found this sponsored mod in the enables a auction house in the maps.
This seems like a good way to trade with other tribes and create new dynamics on the server since tribes already trade between them, this will make it easear.
And since it is a sponsored mod should have some what good support.
I dont know what is the interest on the community for this, i give my support.
