Hey.
The rules as posted are current, there's not really been much need to adapt them further; ofc, Pokécommunity's general rules also apply.
So long as the cursing and the humor doesn't cross into the particulars posted in the thread there shouldn't be much issue. As a general rule, remember that since this site is accessed by a general public, if your story touches upon anything that goes past K+ rating it *probably* needs warnings; if it touches upon stuff that goes above T, *definitively* needs warnings. Cursing and that kind of stuff can be used sparingly. Mindful of what counts as "middle school" humor since that can get touchy on aspects such as hazing and bullying, which *absolutely* need a warning. When in doubt: as the thread says, you can PM a mod with a sample of writing, for example.
