Trial
From Graal Bible
The name given to accounts which have not yet paid any money for special privileges. These accounts cannot save their attributes on any servers, and do not have any access to hosted playerworlds not visible on the Classic tab.
The fact that their attributes reset after each logoff is a constant source of annoyance to server managers, as using trial accounts is a common method of avoiding bans and jails. Many scripts have been designed to keep trial players restrained, with varying success, but many servers simply opt not to allow trial accounts any access whatsoever.
A Trial account can be determined through script with the "playertrial" flag.
