Tokens are a form of online currency. Once you buy your first token package, you become a Green user.
Using tokens to get the attention of your favorite models is called tipping and they are useful especially when you would like to make a special request to a model or simply to show your appreciation and admiration. You can also use tokens to enter Private, Cam2Cam, Spy and Group shows or to simply purchase model's photo/video albums.
Another way to use your tokens is to send offline tips to your favorite models as a gift and include a special message with the tip to surprise them.
Even though tipping is not required, users can praise a model's show by sending them tips. Models usually respond better to users of unique requests after being tipped and feeling appreciated.
You can purchase tokens by clicking on the plus icon next to your username and your balance will be shown on its left once you make your first purchase.
