THE

From KefkaPedia

THE is a capitalized version of the word 'the'. It implies supremacy to the word or phrase that it precedes. One might say "Craze is THE guy to get faulted most. He's such a narnar.

For Example:

THE RPG and THE Forum are both owned by Systemeth. Their names imply that of all the RPGs and Forums there are and ever could be, these are THE single most important ones.
