Hello...

I'm playing with plone, but this is really a zope question. At the moment, =
I=20
want to give my users the ability to choose whether or not they receive an=
=20
email when a certain object type is published. The way I'm looking at doing=
=20
this is to allow the user to choose whether they have a certain role or not=
=2E=20
Naturally, these would be custom roles, but I want the user to decide=20
(without my intervention) on if that person wants to have that role.=20

Anyone have any ideas on doing this?

Thanks!

Russell
