You Letter for August 2004" represents a payment made in that month of that year). Users are then able to open these virtual letters to choose one of two or three limited-edition items to be granted into their inventory from each letter. These items were known as Donation Items until potential legal problems prompted the name change. Monthly Collectible items and the "Thank You" letter items they are found in are specific to the month that they were released in: for example, the items found in the "Thank You" letter for April 2006 can only be found in that letter, and one could only purchase that letter in April 2006. Letters can be purchased over the phone, with a text message from a mobile phone, via PayPal, credit card, traditional mail or with Gaia Cash through the Cash Shop, "La Victoire". Envelopes and letters can be later bought and sold through user trades or through Marketplace.

Games will vary depending on the RIG – some may require users to choose a
