I installed Wordpress 2.8 by the one-click install method. The site works, but I don't know why (isn't that strange?). I told the installer to put the installation in a 'wp28' directory, and sure enough, that is where the URL must point, but I don't see the 'wp28' directory in my /home/username/sitename.dreamhosters.com/ directory. So where did it go? How would I install new themes and plugins?
