When someone submits an event they get a response, this response comes from an email address that cannot be changed and i'm not sure when it was set in the first place. If we can change the email address where new event notifications can go, we should be able to change who the event confirmations come from, and if the from email can't be set these two values should be the same.
This idea has been addressed on the new timely web application. Try out during private beta at https://ww.time.ly/new
