Styles are contained in documents and templates. Chances are that the styles
you are talking about are in your normal.dot template. Find that template
(or the template that does have your styles) and from Windows copy it to a
floppy drive or a network location. Rename it to "ReedStyles.dot" or
something similar because you don't want extra normal.dot templates floating
around.

The others can use them by creating new documents based on your template.
The styles can also be copied to other templates including their normal.dot.
Existing documents can be attached to your template to access your styles as
well.

A couple of questions, though:

Why did you create new styles instead of modifying the built-in heading
styles? The built-in heading styles are treated specially by Word in ways
that makes them very handy.

Do your styles contain numbering or bullets? (If they do, special steps are
needed in forming the styles and in transfering them.)
