Here are some ways I use to make money,
Go ZOMG people!!!
Get down and dirty and kill some monsters! xD
Dungeons in ZOMG makes heaps of money too just ask around for crews.
The other way is to play booty grab. All ya gotta to do is grab booty xd
Go to the Gaia aquariumm Forum and you can find lotsa glowing tanks!
So go and around and make some money you will make a lot of friends on the way : )
I can assure ya its actually more effective than asking for donations. Of course making a quest thread on Charity/Quest forums is useful too so people know what you are working on...!
