What exactly is the 321 rule?

Fediverse streetpass would go craaaaazy

Yep I sure did the thing you said not to do. I’m very new to a lot of this stuff still learning, I didn’t think about it and thought it would just work in was able to recover all my files and everything is fine so I’m not worried about it anymore and I understand the issue now. So this has just been a learning experience, I’m moving on with the second message you suggested and just making a new folder and copying stuff over. Thanks for the input man

This is so true good comment
