I've having to get a cron job that's currently working on MediaTemple (Grid Service) to work on a new 1&1 Internet account. I've yet to do this yet, but is there anything I need to take into consideration? Or... effectively... cron jobs are cron jobs, they'll work where ever?
It's a cron job to send out a mailing list from a database.
Anything I need to consider to make it work smoothly?
