Gaia has recently added some new emotes to the forums and guilds. To access most of these, you simply click the dropdown that says "Normal". You can change the category and select from some very fun new emotes! BUT! Gaia made some of them hidden. Here is the list I found of hidden ones. If anyone becomes aware of any more, post them in this thread.
