drag 'n' drop??

As we discussed on Friday we though it would be easier not to have the drag and drop as it will be more time consuming for the user to type out the message then click on the message and drag it up to the name they want to send it too and also they could send it to the wrong person if they do not drag it to the right button. but as we are all meeting on Tuesday we can all discuss this further if anyone has another opinion.
