We are working to make our internal issue tracking system available to the interested public. This system has been in use for some time for the Astrogeology users and developers to track issues related to the ISIS software suite. We will be adding features and making new content available a little at a time. The move to making this public is likely to include some hiccups, so we are leaving the previous support forum open until we are sure this one is working well. Please let us know if you are having problems.
