You know what's cool? Custom emojis! 
Like this infinity heart. Figured this was a good first emoji for a poly group.
Send me more ideas and images for custom emojis. They have to be under 50kb png files.
@Jerrik love your emoji
@Padme Thanks, I made it myself. This platform let's us make our own custom ones. If you have an idea for another let me know.
Also: Welcome to our little community!
@Jerrik how do we use yours and make our own?
@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)
@Jerrik didn't know that's possible. Cool stuff!
