Token Templates are a standard feature of DotNetNuke used in simpler modules. It's a convention for simple placeholders like this [NameOfDesiredContent] to be replaced with the data at run time.

Actually Tokens can do a bit more: they support multiple data sources. So the real tokens usually look like this [DataSource:NameOfDesiredContent]. Some data sources are part of the DNN-Standard, and 2Sexy Content adds another one called Content. So the data sources available in 2Sexy Content are:

1. Content
2. Request
3. PortalSettings
4. User
