(This is not the) Sticky: How To Turn Off Tagging If You Want To Do This
"If You Want To Do This" -- One of the dumber things I've seen in a topic title. It's like totally 100% completely redundant. Dude.
There are too many stickies in this forum, so nobody is just going to sit and read them all hoping to find an answer to a random question. The title has to mean something. The word "notification" is nowhere to be found in that sticky title or body. You should add it so that it at least comes up in a search.
I have no idea what it means to "turn off tagging". It's not explained on the settings page and not even explained in the sticky.
