A strange question no doubt, but I've not been able to find the answer elsewhere - I suspect it's 'no'.
I'm in a situation where, as well as on-site development where developers interact with JIRA as normal, we have off-site development being done where those developers don't have access to the management network where our instance of JIRA lives. Sounds counter-intuitive I know, but stay with me that's what I have to work with.
JIRA is used as it is intended, and reported against, but we're nearing the user limit of our current license. I'm not interested in trying to circumvent licensing and we'll upgrade if that is the only way forward. But, before doing so my question really is about whether there is a mechanism for representing non-user assignees in JIRA without consuming a licensed seat? If so, how do I do it?
