There are several formats which are likely to meet everyone's needs.
Text would do, assuming that we are discussing content rather than
format. PDF documents can probably be read by everyone on the list,
but I realize that not everybody is able to write to PDF format, which
is a disadvantage. HTML documents can be read by anybody, regardless
of the OS or office suite they use.
