This is probably a stupid comment, but...
I was thinking that it would be helpful if when I click on the search link, and I come to the search page, for the cursor to be defaulted into the search box so I can just type and hit enter.
Currently, I use the mouse to click the box to get the cursor.
It's not a real huge problem (and I imagine it woulnd't be too hard to change), but I just think it's a little annoying.
Thanks.... and keep up the good work!!
