TiddlyWiki class definitions are prefixed with tc- and are mainly used in the "vanilla base" theme. The tc- prefix is reserved for TiddlyWiki, so it should not be used for user defined classes.

Users, especially plugin developers, should use their own prefixes eg: mytc- or something similar.

The following info can also be found in the $:/ControlPanel -> Advanced -> Stylesheets tab
