Before Rey beats me to it :) I typed up a quick tutorial on my first use of Ajax w/jQuery: http://www.thecrumb.com/2007/11/30/fetching-data-with-jquery/
Just like everything else I've done with jQuery it was easy and quick to implement :) Soon as I have some time I'm also going to post the final results of my checkbox show/hide code which several people on the list (Karl, Trevor, etc) helped me with. Jim
