Sweet.  Thanks for the serialize tip!

simple preview link calls preview()

Preview

preview posts the form data

<%= javascript_tag do %>
function preview() {
  $.post("/sites/<%=-lAcQvMfiUYM@public.gmane.org%>/preview",
$(''#add-site'').serialize());
  return false;
}
<% end %>

and I''m all set.
