Can you create an @mention for an email address?

[Andrea Landwehr]

If someone wants to comment on a service desk ticket and include a non-registered user email address, is there a way to that? We don't have all our users setup as service desk customers so sometimes, when we want to include someone (other than the reporter or watcher) in a comment, we need a way to be able to add their email address.

Unfortunately if you are in the service desk then you will have to add them as a customer first.  If you are replying to a service desk email you can add them on the cc line and it will create the customer for you and they will be included in the reply.

Ok - so replying and adding an email address in the CC will prompt them to create a user account? It doesn't just share the ticket with them?
