TATRAS (Teach America To Read And Spell - http://www.verticalphonics.com) produces a phonics program called "The Great Saltmine and Hifwip Direct Phonics Reading Program," which falls into a category called "vertical phonics." This means that all sounds of a particular phonogram are taught together (eg: a, ay, ah/aw) instead of teaching short sounds and then long sounds, etc.

This group is not officially affiliated with the producer of the program (TATRAS), but was created to enable homeschooling parents who are using the program (or interested in using the program) to discuss their experiences, ask and answer questions, etc.
