On JAC, the Seraph project has group 'atlassian-developers' assigned to the 'Developers' role: http://jira.atlassian.com/secure/project/ViewProjectRoleActors.jspa?projectId=10480 The 'atlassian-developers' group has 89 members: http://jira.atlassian.com/secure/admin/user/UserBrowser.jspa?emailFilter=&group=atlassian-developers However, against the project in the 'View Project Role Usage' screen, it shows only '1 member'. Presumably, it's counting the group as a single member when it should be counting the number of users in the group. This confused me for a few minutes. I thought the role was incorrectly configured, but after a while discovered that I just wasn't in the group.
