Yes, very unfriendly. I have only just realized this change in invitation procedure: our former default invitation message now needs to be manually selected each time. We've been sending out invitations lacking our custom text for some months now without noticing it, I guess.
Anyhow, there needs to be an option for a default invitation message, not just the "no message" default. I'll try to comment the suggestion in beta if that is worth anything...
