There should be a clean page on which to globally change the account's postal/mailing address used in e-mail footers, so that this doesn't have to get done manually or through templating. Most users I imagine do not even use templates, but simply copy old webinars...Even when picking a new template, the system is pulling in an old address from other webinars as if it were a global setting already. If it were simply coded to be blank, this would eliminate the problem too, but a global change capability is the professional solution
