windGuide: Stamps
By finding secrets, completing challenges, and achieving various goals, users can unlock stamps for their stamp collection. Stamps provide both a record of achievments and a way to decorate and customize user bios, room descriptions, and forum posts. Every stamp also has a small monetary reward, so that every time a stamp is unlocked, a small amount of dopcoins are earned.
Once you have met a stamp's unlock condition, that stamp is added to your collection and can be inserted into any editable text that supports BBCode. To insert a stamp, type the stamp's name surrounded by :colons:, or open the Stamp Collection section under the text box and click on the stamp you want to insert.
Different stamps have different unlock requirements. Some are very easy, such as summoning with a certain aspect; some are straightforward but challenging, such as raising a specific form of a creature; and some are secret and involve rare items and hidden mechanics. While many stamps have their unlock requirements written in the stamps page before they are unlocked, others will simply have a string of question marks, and there are some rare stamps (especially ones involving seasonal events) that are not listed on the page at all until they are unlocked.
In the case of stamps that require raising a specific form of a pet, the stamp is unlocked upon viewing that pet's room or scrapbook page. This means that even if you released a pet before a corresponding stamp was added, you can still collect that stamp without having to raise another pet.
