Re: Undeliverable Email - Alternate Email address

"As you have an Acrobat Sign individual service level plan, the manage page is not available for you."
As a novice user trying out the e-signature application, now troubleshooting a bounced signature request after a user changed his email address (the old email address bounces), I've found information suggesting that I might -- maybe -- be able to access a management panel to change the email address and continue with the signature request workflow (which involves multiple sequenced users that need to sign). That I can't find a management console with that kind of functionality, and that it might be hidden from view because I don't have the permissions level required at a higher level of service, is frustrating to the point of intolerable -- and an caution that I shouldn't use this feature in a professional setting (or Adobe at all).
