We have a group of people in our company who do some testing for us a couple of times a year for 2-3 weeks. We'd like for them to be able to submit child issues (Bugs) for one particular epic, "XXX-9999 Testing". There's no other reason they would need Jira access the other 46-48 weeks of the year so it seems silly to make them Jira users for these few weeks twice a year when they don't need it otherwise.
Is there a way to have them submit their issues without being Jira members?
If so, what is the best way to set them up to submit issues?
