I've got in touch with another administrator dealing with the emotes of the wiki's chatroom. We agreed that the list is very long - usually filled by emotes that are never used.
So starting immediately, the emote list has been reverted to Wikia's default.
You must be asking, Why?
We're starting from scratch. If you want to request an emote, please request here. This should be able to recognize which emotes are actually being used.To see the revision with the emotes and all, check here.
Note: Emoticons are entirely administrator discretion.
