At Orchid Heights regions we offer
Gloebit and Podex currency
Podex offers virtual currency that can be used on the grid they where bought. If you like to use podex on different grids with different avatars, you will have to create a new account on each grid or transfer the money from one avatar to the other.
Gloebit is a virtual currency that can be used on different grids on gloebit enabled regions within OpenSim. You can add all your avatars in Open sim to this account, no transfer of money needed from one to the other avatar. Gloebit allows creators to sell to people from other grids, because the sold items can be taken home to the grids they come from and used there.
