Beta 2 will bring much more stablity to BuildaSearch.  The new search backbone is already in place, but not accessible to the public as of yet. Custom search engines will be allowed greater customization. Our main focus is to allow anyone to build a custom search in minutes instead of hours and without having to write a single line of code, all while providing a great search service.  You can embed BuildaSearch to a blog or any site.  example here: http://www.buyandselljeans.com

I greatly appreciate your feedback! 

Will add the underscore issue to our bug queue. BaS has been tested on every browser except (IE), and we have not encountered such a problem. Anyways we have rebuilt about 90% of BuildaSearch for the next release, with tons of new features.  Are there any features you think we should add to BaS? We may be able to add them before the beta 2 release. 

The underscore issue only occurs when you try to edit is that right?  What happens if you copy and paste the list below and click "save changes"
