What I realized is that wizards on the same account can share different types of items between themselves with the shared bank. What about gold? My wizard has lots of gold, some of it I don't really want at the moment, while my other wizards are broke and are in need of money. You can share clothes so that broke wizard could go to the Bazaar, but what happens when there are no more items to sell? I think wizard101 should have the ability to share gold with the shared bank, so that none of my wizards are "gold-lless" when it is time to buy them new gear.
You can, however, move gear between wizards so that they can share the gold that way. That's how I do it--when one wiz is gold-rich, I simply move her recent drops to some of the others so that they can share the wealth.
