Ok, Well I have a Namespace that contains a Learning Guide about all softwares used by a company. They have a mailing list team@domain.com
that forwards to all their team members. I would like to subscribe this mailing list on the namespace so that if I make modifications, all the team members will be notified.
I do not want to send that mailing list all modifications from the entire wiki, just the one namespace. And I want to use their mailing list, that way I don't have to maintain all their contacts.
