Rank Stamps.
Like stated in the [ Ranks ] post, earing points is pretty simple when participating in roleplay challenges and hunts. These stamps are what the approved members are given and are able to post up on their intro profile here on Beyond_Ivalice.
How the stamps work are just as simple as gaining ranks. In order to gain the next ranking stamp, you need to - of course - rank up your character. Each and everyone who are approved on this site all start off as a Moppet, and they continue on from there, ranking up on their own time. If you need more information on how the Ranking points work or anything else involving Ranks, Stamps, etc; feel free to comment and let us know what's up.
