I am very excited, as I seem to be making progress -- if one equates motion
and progress

I followed your suggestion ... a number of times, before I saw where these
user-defined lists show up to be invoked. Now I have several redundant styles
in the "List Library" pane, and no apparent way to delete them. I am betting
that there is an "intuitively obvious" way to do this, but my intuition
regarding Word is suspect of late. Can you help?

Thanks for your patience!

p.s. I notice that the box to "Notify me of replies" appears to be cosmetic
rather than functional .. at least when using Firefox as the browser.
