I'd like to set up a separate module/support cases and portal to use as a ticketing center for an internal helpdesk for my IT Department. How would I go about setting that up? And can I customize it to make it look like a nice webpage or interface when users want to check the status if their tickets? I'd like users to be able to submit requests via email or a portal, or through the ERP. But I want them to receive email updates when their ticket has been updated/changed/closed, etc. Basically, I want it to be used like any other ticketing software out there. Has anyone else done this? How did you do it and what are your thoughts? Thanks in advance!
