Can I make cron scripts execute as my projects user?
No, not at the moment. The project user cannot login and doesn’t have a valid shell. We’re afraid that you’ll just have to nominate a project member to be responsible for running project cron jobs at the moment. Please try to be sensible with the frequency and timing of cron jobs – don’t run them every other minute, don’t run them all at the same time, and (if you can) run them in the middle of the night (for Europeans and Americans, I suppose – we don’t have many users in Asia at the moment).
