Hi Alex,
Thank you so much for your quick response (I was seriously prepared to wait for a week

)! Let me see if I understand this correctly: are you saying that I could have several "Email - List" drop-down menus on the same form? So, say, there are three menus each containing three options (e.g., Group 1, Group 2, Group 3), and the user can choose Group 1 from the first menu, Group 2, from the second, Group 3 from the third, then submit the message and it will go to all three groups? This is how I did it on the site:
agniinstitute.cloudaccess.net/index.php?...ssage&pf=5&Itemid=73 , is this what you were telling me about? If so, how will the user be able to send a message to one or two groups only? Is there a way to put a blank field in the drop-down menu, so that the message doesn't get sent three times by default?
Thank you again, I really appreciate your help!
