I have released a new project on OpenNTF.  The ASND Mass Mailer is something that I had built for a previous employer to solve the problems with maintaining groups for communication purposes.  Instead of using groups to send out company wide communications, it uses information in the person documents to generate a list of recipients and sends out individual emails to each person without bogging down the router with having a huge BCC field.  Although there is nothing earth shattering about the code in this application, it's simplicity and usefulness should make it something you can easily deploy in your environment.
