Tracy,
Bookshare has no plans to drop BRF. Jim is just in the habit of only
mentioning DAISY, and every time he does someone asks this question.
Whenever Jim or another of the Bookshare staff refers to the ability to
create DAISY they are always implying BRF because both are created as part
of the same process. According to what Engineering told several of us, the
RTF file is processed then both the DAISY and BRF books are created from the
intermediate file.

When you say it's easily converted to Daisy, do you also mean BRF? I do
not want braille to be the poor forgotten stepchild it often seems to be.
