Fix minor issue with merge to develop branch related to add/remove members

Hi Dan:

Pull request with missing fix in the merge related to add/remove member, cycle (for sending email) as well as remove duplicates.

Used Email instead of Email_Now in notification type. Emails will not be prepared if it is invalid notification type other than Email_Now or Email_Digest.

Please merge this for this sprint. Thanks.

Regards
Mouli
