You are right, that option does not seem to exist. There is an option to enable that feature in the admin panel:
In your admin panel: Go to "Settings">"Advanced Settings">"Others" allows you to check the box for "Enable TinyMCS in comments".
However, checking this box does not affect the comments system for Articles.
What "comments" section is this referring to?
I am wanting the tinyMce to show up when you comment on articles. Ideally I would like it to work the same way for all sections but I am most concerned with the articles section as we have turned it into a special section that receives an abnormally high amount of traffic on our site, due to our modifications. Thanks for any help JL :)
PS = Just checked I do have that option checked and it doesn't seem to make a difference within the articles module for whatever reason. I also noticed that when attempting to post a video comment everything works up until it is time to hit post then it doesn't light up at all??? No idea if it is the articles module or how the comments module is interacting with it....
