ASLwrite (ASL: ) is a writing system that developed from si5s. It was created to be an open-source, continuously developing orthography for American Sign Language (ASL), trying to capture the nuances of ASL's features. ASLwrite is currently used by no more than a handful of people, primarily revolving around discussions happening on Facebook and, previously, Google Groups. However, it is currently spreading, with comic strips, posters and more becoming available. Since its creation, it has evolved to include more digits, locatives, movements and marks as well as modify those already present.
