[galaxy-dev] How to delete user (and unshared files) in local instance by galaxy-admin (panel)

Hi All, We are finally up-and-running again with the latest dist release. The previoous version was ok but already quite old. For our local public server at wur we are now encountering the awaited disk space issues..... as had to come some day....but sooner anyway... So we have been cleaning up. Used the cleanusp scripts for marked as deleted files and such. But two issues remain for galaxy-admin users: 1) How to really delete a user and its non (no-longer) shared files? (from the admin panel) 2) Is there a way to get the user disk space usage in the admin panel (or using some other method?)? Thereby we can contact that user to push cleaning up files. Thanks Alex
