Global Site Search

Plugin seems to be working just fine Need help with a couple of things:

1. I was looking to add the global site search field and button to my front page, when search is executed then go to the /site-search/ page.

2. Can I add global site search to each new users sidebar or seomthing like that? Would almost have to be something that is theme independent, possible a default txt/html widget? .......................damn admin bar for wpmu would come in handy!
