The Toontown Rewritten rules can apply here too!
Be Respectful of Other Toons! - Don't be rude, use foul language, and bully others. Also, don't attempt to ruin other's topics in an attempt to be mean, because it ruins it for everyone.
Take It Easy! - If you don't like someone's project or post, or don't like something they did, don't be mean. Instead give criticism, and be nice.
Chat With Care! - Don't try to bypass the chat filters or use an inappropriate username! It's never nice to be inappropriate,
Don't Be Annoying! - Don't spam the forum with unnecessary topics, point out people, or harass others.
Protect Your Privacy! - Don't share personal information of any kind! The last sentence in the picture above is good, too!
I think that if you practice internet safety, along with following the rules of HSF, you'll be a superstar online!
