The press release for DL 3.2 lists as a bullet:

"Streamlined setup process including email user invites"

I'm not sure what the setup process has to do with email user invites, but does this mean that the new relase includes the ability to send meeting invitations by email to non-DL users (via .ics files)? If so, I can't seem to figure out how to do it. If not, what does "email user invites mean"?
