I joined the CoU project in early 2014 after watching the development process. I contribute code (like the recipes feature), helped write our forums software, and manage the website and profile pages.
One of the features we’re working on for the next update is a selection of preset avatars, provided by Glitch players, to copy. This is temporary because building a customization and animation system from scratch is a lot of work and a very long process, so this is to tide everyone over until we get time to do that. Anyone can allow their avatar to be listed, just contact us with your Glitch username and we’ll add it.
