I have a mailing list in a Postgres database and I want to give my users the ability to unsubscribe from mailings.
I wish to send out emails with a link to an RoR website to handle the unsubscribe.
Is there a document anywhere that describes how to do this properly? That is, what the link in the email should look like and what the controller(s), routes.rb, and view(s) should look like?
Do I need to do a (implied) DELETE verb anywhere?
