I don't find the lookup control appropriate for this particular case - i would like to keep the "send to" field as a long input with values delimited by some kind of delimiter - I don't want a pop-up to show up.
There is a
jQuery UI widget which I will probably use. Maybe you could keep my problem in mind and include it in a future release.
Anyway, thanks for your swift answers. Take care & congrats on a pretty awesome project. ;)
