OK, I took Andrew's suggestion and looked at UserManager. I
combined some
of that code with the javadoc example in the WorkFlow.java source
and came
up with the following very simple but working example. It sends an
email,
waits for a member of the Admins group to make a decision and then
sends
another email (I said it was very basic). It's pretty easy once you
see
it and I thought I would post in case anyone else was wondering
about
workflows.

Re: workflows - examples?
Louis, Bob--
Probably the best example is in the PageManager code; we use the
workflow service to route page-save operations if approval is
required. UserManager also creates workflows if approval is required
for new wiki accounts.
