I make the journals readonly, so that users can't accidentally overwrite the existing journal file.
The other approach I'm using in JMP 9.0.0 is addins with menu customization (instead of journals). Users really appreciate the menus - they don't have to search for the journal file to run an application.
I should have been more clear. I am generating multiple reports and appending them to journals. I then save the Journals as .jrn and .html files for users to view. The reports get generated on a daily basis, but currently I have to manually intervene to allow the script to save all the journals.
