This probably needs some custom coding
I am thinking of implementing this with specific bb codes to hide content that is then only available for admins or moderators
Xenforo coding is pretty new to me, so help is appreciated.
I think I can create something when I know how to
1) Get the current post_id in a callback that parses the bbcode
2) know how to check if a post_id can be edited by the current visitor? (either they are the creator, or they have edit/moderation permissions)
