If you are using [tag]Safari[/tag] and accessing this site, I am sorry to report that the Search does not work. Safari throws the following error:
Bad Request
Your browser sent a request that this server could not understand.
Request header field is missing colon separator.
While I am working on fixing it, I think you should do the world a favor and get an optimized [tag]browser[/tag].

Done!
The issue was caused not by the search code but by the quicktags code I was using. I disabled that and instead installed the WordPress Plugin Comments Quicktags to achieve the same result.
Thank you for your patience!
