I'm getting no where with this, are there any other suggestions on row
to render a 'please wait' page while other python works? Can I call a
view.my function to run from my 'please wait' template?
Please be as elementary as possible as javascript, AJAX, jquery, and
the like are brand new to me.
Thanks,
Bradley
