We've just moved over from ZenDesk and were surprised to learn that issue collectors can't handle unknown users (i.e., the submitter needs to be a defined user before they can be listed as a reporter). And if the submitter isn't listed as a reporter, they don't get automatic notifications, which is one of the primary benefits of a ticketing system! (Otherwise it looks like we have to manually create user accounts for each unknown user that comes in - and then add that new user to the Reporter field - which really isn't tenable.)
Does anyone else use Service Desk as a ticketing system for a SaaS application, or is simply not designed for that? Is there an alternative to creating a form-based help ticket interface - other than an issue collector - that I'm overlooking? Seems like a basic feature to have...
Thanks!
