I know this is an older thread, but I have a suggestion for future versions which relates to this.
When we first got SmarterMail last month, I was under the impression that if I invited attendees to a meeting and they accepted my invitation, that the event would be added to their calendar...but that doesn't seem to be the case.
It would make much more sense if when an attendee accepted the invitation, that they didn't have to manually create the same event in their own calendar...right??
