I don't know if "read receipt" is the exact word to describe what I want…
What I want is that when I publish a document inside a space, an e-mail is sent to the subscribers of that space (I know this can be done with a rule). In that moment, I'm sure that the subscribers will know that there is a new document (or new version of a document), but I can't be sure that they have read it.
I want to be sure that the subscribers have downloaded/read that document. I suppose that can be known, because Alfresco knows (for registered users) which user access which document. That's what I call "read receipt", a list of users which have downloaded/read the document. Does Alfresco offer this functionality?
Thanks again.
