clarkwinkelmann There's a contradiction here because the permission Edit users partaking in private discussions, even if enabled for moderators/admins only, would be meaningless because admins/mods can't see private discussions of other users to be able to edit the participants. It would only apply to private discussions where the admin/mod is participant (BTW I tested that, to confirm it). Users on the forum would ask for the ability to add new participants in private discussions after they are created and if the admin carelessly decides that the Edit users partaking in private discussions is the one to enable to all users (which is what I did), then a huge problem is created. Yes, users will now be able to add new participants to private discussions, but then anyone would see a new option for public discussions: to edit the participants, effectively rendering them private. What is more, even if that is done by mistake, there's no way to make them public again, unless tweaking the DB of course. I think something should be done, it's a dangerous option and I am grateful to a user on my forum for actually discovering this and warning me, instead of me realizing it the hard way...
