invitee list isn't properly updated when someone joins
When someone accepts my invitation to my group, they are not always removed from the list of invitees (depending on how they join the group, I guess). This happens even though the email of the new member and that of the invitee are the same. Anyhow, I am trying to keep track of who I have invited and who has accepted, so I remove *members* from the list of invitees. This sends a letter to the invitee saying that the invitation has been canceled ... but they are already a *member*. This confuses everyone. Either
1) the list of invitees should recognize that an invitees email corresponds to a member's email and the invitee should be removed from the list of invitees.
2) I should be able to remove someone from the list of invitees without automatically generating an email to the invitee saying their invitation is canceled.
