g (roll option)
[ ] Display to GM Option
[g: ], [gm: ] evaluates the text after the ':' but only displays the results to the gm, such as:
Everyone can see this [g: "but only the GM can see this"]
This roll option may be combined with the [s:], [w():], [gt:], and [st:] options. Blank messages will not be shown to a certain user if an entire message is invisible to that user due to these roll options or the [h:] roll option.
