@Padme If you're on an app, you can use the emoji button on the top right (rather than the one built into your on-screen keyboard). On the regular site, the emoji selection has a "custom" area.
I think only I can make custom ones (maybe @JoshRollins too since he's a mod, but I'm not sure) so if you have a good one send it to me as a .png file under 50kb in size and what the coding for it should be (if you care, otherwise I'll just come up with something)
