How to change all scripts and form alerts to a single user

Each script’s alerting process is controlled individually.  You have to go into each one and change the options in the “Unhandled Errors” tab.  To fill out a specific email use the “Notify Emails” box.  Best practice is to setup a group for the people that you want getting script notifications, and assign that group to every script with the “Notify Group” field.  Once you’ve done that for all your scripts, then you can add/remove users from that group without having to go into each individual script. I’m unclear on what you mean by “form alerts”.
