Admins can customize the chat emoticons on their communities by editing that page. Emoticons can be any standard image file type, should be hosted on Fandom, and must be 19 x 19 px in size. If they aren't that size, they will be scaled to it.

Note: quote marks (") cannot be used in emoticon shortcuts.
