My partner and I both have Crusher accounts. I started to create an invitation by putting in the basic info. Then he signed on under MY account (I did not know yet about the "co-edit" feature) to customize the page graphics.
I then added the invitees' addresses, typed a personal note and previewed it. Everything looked fine. But after the email was sent, the subject line said that the invitation was coming from HIM not me. I don't know how this was possible, as he had never logged in under his account. Worse, I can't figure out how to send a correction email under my own name. Everything I send from that page comes from him, and most of the invitees don't know who he is and I'm afraid they will ignore the mail.
