After some additional thoughts about how to solve it why not do it this way:

1.) Give a clear indication if a follower is set to "Receive Messages by Email: Never" e.g.: like write his name in red in the follower list or add a big red X over his picture - so we already know with one look who will usually NOT get an E-Mail.

2.) If i push the button "Send a message" all Followers are listed with checkboxes - just like it works when you click send a message for an opportunity - BUT all the partners set to "Receive Messages by Email: Never" should be unchecked by default.

If i "override" this checkbox and set a followers checkbox to "true" he will receive an E-Mail no matter what is set for "Receive Messages by Email: Never" - This way we can "temporarily" send a partner an E-Mail even if he normaly will not receive E-Mails.

3) After pressing the Button "Send a message" and then click on the symbol to "enlarge" the message a new E-mail form pops up. The problem with this form is that it says "Followers of xxxx and". Again you would not know who will receive a message!

To solve this i would suggest to remove the line which says "Followers of xxxx and" and instead add all followers that had checked boxes in point two of my suggestion as recipients in the To: field. This would reflect very much the behavior of point two and would also allow to temporarily add recipients even if they are set to "Receive Messages by Email: Never"

This would work for nearly all cases perfectly and has the advantages of:

• clearly see in the follower list who will receive messages
• allow temporarily to send information to the partner even if he "normaly" will not receive mails
• visually see through the "checkboxes" or the "receipient bubbles" in the mail form who will receive mails
• take out the guessing when sending E-Mails

Please feel free to give your comments - if somebody knows how to show this "idea" to openerp pleas tell me!
