we need more emotes. specifically, the Wow Alliance emote! we have the horde one already but no alliance one.
For general emoji suggestions, this is a good place. For something game specific, you’ll want to make a chapter request in the CL section. Any emojis must be legal and free from copyright. Press kits are a great place to find some.
They generally should not have a background, be JPEG, PNG or GIF, preferably 128x128 and less than 256k. They get resized to I think 32x32, so consider that when requesting. You want to be able to see it.
