I installed WordPress in a subdirectory in my hosting account (/wordpress), just to experiment with. But now that I have a bunch of content loaded and the template customized to where I want it, I tried just pointing my URL to the /wordrpess directory. So now http://www.mysite.com points to /wordpress, instead of /. Now my stylesheet is lost, even though WordPress seems to be working fine otherwise when I go to http://www.mysite.com. What's wrong, and how do I fix it?
