I've got to agree with Andrew about that, but I want to add support to Ken's request for improvements to the way the question of sending to email queue vs sending now is handled.

I've heard several users complain that they always have to click on 'send now' in PO because the default is always 'to the queue'. It would be nice if the behavior was consistent between the modules that offer the feature(as the default is now in OE), and even better if it remembered the last selection of each user to base the next default selection on (or at least offered some control like what Ken suggested).
