Interesting question, Paul. If I enter one number, then go to the message area, it wraps the number in a box and adds an "X" to remove that number; then I can add another number, go to the message box, and it adds the number and changes to a "Group Conversation". But, I need to go to the message box in between for it to recognize a separate number - very clunky. **Update - if you enter a phone number, then hit Shift+Enter you can then add another, and another. I still dont' see a way to "Save" the group or enter it from a cut n paste list.
I've been playing with it but I haven't found the magical formula for doing this easily. I'll let you know if I figure it out!
