This answers my question

Besides being able to privately flag things I dont see an option to mark them publicly like that

Thank you Norman.

@Garry might know differently

I’ve just installed a new plugin. Hopefully you should now see this at the bottom of a post if you’re the OP:

Let me know if it’s working @anon18404023.
