Charities are organizations created for the sole purpose of helping Gaians on their quests. There are multiple conditions to which a charity runs on, and in most cases, charities also require donations from time to time to keep up with donation requests.
Each charity has its own set of rules, so Gaians must be sure to read each thread carefully!
A Quest is the name of a Gaian's goal for an item (or items) within Gaia Online. Quests can be minor or major, depending on a number of conditions, such as one item's worth or the number of items quested. An organized quest is created via a Thread, or via one's Signature.
