@Prof_Harley I would say that https://mastodon.help/ would be a good starting point.

The high-points are:
- Use hashtags
- Show kindness and acceptance to everyone ("Don't be a dick")
- To find people to follow, look at the following list of people like yourself
- Use the CW (Content Warning) when you think it is appropriate
- Follow your server's rules (https://mastodon.social/about)
- Use the report feature to report folks to the moderators when you see them not following the rules.

Enjoy! 😀
