(I don't know where to put this, I'm sorry.)
In my error logs today a specific IP was searching ALL OVER for this file - in what looks to me as the assumed possible installation folders (i.e. /wordpress, /postnuke, /tikiwiki, /weblog, /blog, etc.).
I'm curious - what is this file? What does it do? (I'm sorry if this is a stupid/obvious question.) Should I be worried about security. I mean the file isn't exactly hidden - it's exactly where it would be expected to be when WP is installed in the root of a site.
