Rooms who's owners are gold site supporters are now able to add custom emojis! Room owners themselves can upload emoji, but permanent moderators can too. Emoji can be used by anyone in the room.
The upload form for emoji can be found on a new room settings page, which can be found at
jumpin.chat/<room name>/settings/emoji. Here you will also find a list of all the current emoji as well as who added them.
There's no limit to the number of emoji you can add, so be sure to upload plenty! Do note, you can gift support to a room owner to give them gold for an amount of time, so the burden is not entirely on a single person.
