I don't know if you are familiar with frameworks like RoR or CakePHP,
but they have classes called helpers. Both frameworks have a
prototype/scriptaculous helper built in to them. I wanted to build a
helper for manipulating select boxes on top of your jquery plugin.
The moveOptions function is critical for what I am trying to do. I
can have people download my modified version of your plugin but I
would rather just direct them to your site so that if you ever modify
the plugin that they can just download it again from your site without
worrying about losing the moveOptions functionality. Sorry to use the
google group to ask you but I tried your gmail account today and I
wasn't sure if you checked it or not.
Thank you,
CodeCowboy
