After the hard disk failure on jthink.net I rethought the location for our JIRA issue tracker. The issue tracker is now hosted by Atlassian themselves (the makers of JIRA) rather than hosting it directly on the jthink.net for greater resilience.
Usernames and passwords remain the same.
Because now hosted on Atlassian JIRA has now been updated to a later version, so its look slightly different but is essentially the same.
Links on jthink.net have been updated to reflect this.
