We are looking at moving to Jira Core (w/ Confluence). We have projects that sometimes involve other companies. If we create a project can non Jira users see a project and mark a task assigned to them as complete or add notes to a task assigned to them? Can a task be assigned to a non Jira user?
Some of the other PM programs allow for that. They just have to register with the service and they have limited access to projects they are involved in.
