Create survey => You are the owner of te survey, then you have all rights in this survey. I really think we must leave "owner"=>All permissions.

I do not agree with that at all. This behaviour could be the default, I'm perfectly fine with that, but I very much want to stop my users from deleting or deactivating ANY survey, including their own.

Any new ideas on this? I'm getting back errors from the remote API because my application thinks that a survey they exported previously still exists but the survey creator removed the survey. Aside from this error, i even think they are violating laws by being able to remove the survey and its participants. I wasted a day manually restoring a survey from a backup because some user clicked the wrong button. I don't want ANY user (aside from the super admin) to have this button!

As an alternative i could probably live with a setting to 'hide' a survey instead of deleting it.
