I'm using Moodle 1.9. I've searched the forum and found Tim's answer (on 6 April 2011) about removing the "thumbs down" icon that occurs whenever anyone types the letter "n" followed by a closed paren:
Note that you can change the list of what is subsituted by going to
Site administration ► Appearance ► HTML settings.
And the Moodle doc for that page shows a nice table with various emoticons (smiley faces, frowns, etc). But in my installation of Moodle 1.9. I don't see that chart. Was it added to Moodle 2.0, or just never installed in my particular instance of Moodle 1.9? Thanks.
