Ok, i'm sorry to write several consecutive post on this thread, but i found a simple change in the CCV_Pinto's code:
Original CCV_Pinto' Code
Code:
if($vbulletin->options['VMEN_active'] == 1 AND $userinfo['field5'] == 'Yes')
Just remove Yes
Code:
if($vbulletin->options['VMEN_active'] == 1 AND $userinfo['field5'] == '')
And create Multiple-Selection Checkbox only with "No"
So, by default all the users will recive the messages. And the question on the Control Panel will be something like this:
Mark "No", if you don't want to recive more profile notifications by Email.
