The normal OG invitation system sends an email to the list of users supplied, providing them with a message about joining and a simple link to the group home page. This presents a number of issues, for example, if the given group is a private group, in which the invitee will land on an Access Denied page. Another flawed example is if a group admin invites a user to a moderated group, which in turn, results in the invitee having to request membership, which then leads to the admin having to approve an invitation that he/she just sent out.
