It would be nice that if an incorrect email addy was entered when sending project invites, that you would get a response from A360 telling you that no such addy exists or was sent back, alerting the Admin or moderator that they need to send a corrected invite, and it didnt create a boghus profile for that bad email addy.
As it stands right now, if you type an incorrect email addy, a profile is still made for that person, which you cannot delete, you can only de-activate them....taking up space on a server somewhere out there......
