These are the general rules:

Both the RP and chat is 3:1:2. That means swearing is ok to an extent (though do keep it within the realm of sanity), sex and related things are only to be mentioned and discussed very mildly, and violence is ok in moderation.
Don't speak about politics or other controversial/too serious stuff.
Be nice to others. Chaotic behavior is ok as long as it doesn't hurt or offend others.
Please don't make fun of people for being gay/trans, etc. If you fall in one of the above categories, please don't make a big deal about it or use your status to attract attention. Pride is ok as long as it isn't used to make people pay more attention to you.
Please don't shitpost or post unrelated junk in the rp threads.
Don't interrupt or butt into other people's rps without permission.
No godmodding, powerplaying, or use of Mary Sues/Gary Stus in order to maintain a fair and fun experience for everyone.
Have fun :D
