Hello ASL Heroes!!!
       Welcome to ASLU!   I'm Dr. Bill.
(Also known in some circles as "Safari Bill"). When not out having adventures I disguise myself as a mild mannered college professor at Sacramento State University (in California, USA).

       I developed ASLU as a tool teach my classes -- so I use the Lifeprint lessons and materials constantly.   Making these resources available to the public has been a lot of fun (a lot of work, but a lot of fun). I'll be the first to tell you, Lifeprint isn't perfect, but hey it's all part of the disguise.
(Click here for more info regarding the development of Lifeprint...)

       I occasionally get email from people seeking to fulfill high school or college language requirements who want to take a graded course and receive documentation. If that's what you are looking for you can click here for information about how to register for an instructor-graded online course that provides documentation on a transcript. If you are a teacher, parent, or autodidact (ha! look it up) check out the links below.

Take care and best wishes.

Many people like to dive in and start learning with "Lesson 1," or check out the "First 100 Signs" mini-tour or the Lifeprint Library.

American Sign Language is a complete, natural language. In addition to learning vocabulary, becoming truly fluent at ASL involves learning grammar, culture, and history.
