We're working with contractors on a part of our product, so we want to restrict their access only to a specific "project" (set of tasks). I've found some results online, but Jira does not behave in the way these pages suggest. For example, one article says to click on one of four possible icons (?!) to connect to Jira. Then it says to click on the Settings link. If I click on the diamond symbol (the only one of the four we've got), there is no such link.
This should be a trivial thing to do. Can someone please tell me how to do it? Thanks!
BTW, I've got a screen shot I could share but, strangely, this web form provides no way to attach one.
