MfD isn't a strict bunch, but when you have been playing together for a while there are things that become accepted as patterns and standards. Might help if they were written down so that new people can have a place to find them.
Rules
Seek group consenses, and specifically GM permission before bringing new players to the fold.
When possible, roll your dice so that others can see them.
Guidelines
When possible put tags in bio sections noting confidentiality level, some examples below. They don't have to be these exact ones, but if you make up something creative please add it to this list with an explanation, or put an explantion on the page you use it.
<ALL></ALL> anyone might know
<LOCAL></LOCAL> local's might know, people in home vilalge or neighborhood
<FRIENDS></FRIENDS> only friends know
<BFF></BFF> only best friends know
<SECRET></SECRET> its a secret, or started a secret at least, i.e. while it shere for Player perusing, your character probably doens't know it.
<TOP SECRET></TOP SECRET> super double secret
