A few rules to keep this a safe space for everyone:
1. Respect/Kindness - no need for bullying or hate. If you don't agree with what someone posted, just move on. No one changes their mind from an internet argument.
2. Appropriateness - keep posts SFW. This is not a place for ads or asking for money. It's a safe space for people to talk about things. Whether they're sad, happy, whatever, this is meant to be a place people can go to for support/positivity.
3. Good Vibes - I shouldn't have to explain this. Honestly, just see the rule above.
