the next time I read about how easy it is to use jquery I'm going to gag ;-)

I finally got it... took a surprising long time to figure this one out

$.post( "groups/add_member/", { "add": ui.draggable.text(), "id": ui.draggable.attr("data-add") }, function(data) {

and obviously added the 'data-add' tag to the <li>
