 Do you run a webring that uses faery ring?  I'd love to know, and add you to the list if you'd like! 💜

+## Maintence

+Due to the relatively small scope and size of faery-ring, it doesn't require much maintence, and I'm not interested in adding very many features.  I'll respond to the any issues and feature requests that are opened, and stay on top of any bugs, but for the most part faery-ring is [passively maintained](https://doc.rust-lang.org/cargo/reference/manifest.html#the-badges-section).
