I've created several custom columns in the Tasks list named NotifyUser and IsUserNotified. These columns are not supposed to be changed by user. I change them programmatically only. Is there any mechanism to:
- Hide those columns from the NewForm, EditForm (I wanna use existent Forms).
- Skip executing workflows when any of those two columns been changed.
- Exclude columns from the notification mails (as long as user doesn't know anything about these columns, there is no need to show them).
