Is there a way to re-invite someone to a Google Group? As the owner of the group, I used the invitation feature to send an invite to a friend of mine. He claims he never received the email (checked his spam folder, etc.). So I'd like to re-send it. However, Google Groups tells me that "no invitations were sent" because that email address was already invited.
I also tried to add that email address directly, but that feature seems to be entirely broken. I can enter the information, but there's no button on the page to actually submit the form and add the user.
Does anybody have any idea how I can get around this?
