When we reply to tickets for our users (customers), the e-mail they receive does not include a link to their ticket in their profile.

Example: We have a company that users have multiple tickets open that are related and when we ask a general question about it they always write back and say "can you please tell me what this is in regards to?"

We added the ticket subject and ticket number to the ticket reply, but the link to the ticket would be quite handy for the end user.
