Hi
while meesing about in the admin section of komention I found the tool tips for the option for users to add Gist code to their comments was missing
COM_KOMENTO_SETTINGS_BBCODE_GIST_DESC
I looked at adding this to your issue tracker but it did not have an option for this.
Also I am use english en_GB if that makes a difference and komento v3.0.4
thanks
