When our members send an "Invite" it's much like sending an email. After all, they can write any message they like and then send it to anybody, even outside our Ning site. But they can not do this when they select "Compose" from their Inbox. Why are we and our members restricted to emailing only within the site? If we can do this thru the "Invite" tab, surely this can be done thru our "Messages"…
