Tagging/rating your campaing 18+ ?

I do not know if this is the right place for this but I am trying to tag a campaign of mine as being mature/18+ but I do not know how to apply the rating to it. and cannot find any explanation on how to properly do it (or even fully what the rating covers, though I still want to add it to be safe)

When you create the Looking for Group listing, you have a checkbox for Mature Content (18+) thanks for the help I already have players though, actually put the rating of the game up to a vote and 18+ won So I guess I should not worry about it then? since the game is not pubicly available

Correct. The designation is only important when putting the game into the Looking for group system.
