Hey how about a gold or point system for players to trade around things?
The gold/point adds with each post (amount is decided by admin/mods, of course).
Like for wolfteam maybe members can trade items. And maybe in MapleStory members can give items/cash to others.
A shop or trading forum can be made for players to trade anything with anything.
This system was used in LogicalGamers but they were kinda inactive so it didn't work out quite well but MHS has potential so it's possible.
Game On,
Giga
