Hi,
We''ve started transitioning to a new, better-named, hopefully-spam-
free group for Prototype and script.aculo.us:
http://groups.google.com/group/prototype-scriptaculous/
prototype-scriptaculous-/JYPxA39Uh5TLH3MbocFFw@public.gmane.org
Could you please post your question there instead? Thanks! People
might still answer here, but probably not for all that much longer...
