First, I want to thank you for giving us allowance to run your excelent scientific codes on the servers you provide. I also apologize if this is off-topic, but i was wondering if a guest could remove erroranous submissions before they are started? This is happenned recently and we dont wish to overload your servers.
Thanks for trying to be considerate to other users.
Unfortunately, there isn't a way to remove the job as 'guest' -- as there's no login information, there's no way to prevent someone from deleting another's jobs. To limit what an ill-intentioned third party could do, we turn off the ability to cancel jobs for people who have not made a ROSIE account.
