Wed Apr 11, 6:01 pm: About the take home: Make sure that in addition to your 198 folder you have a web page (e.g., index.html) in your /pub/YOURDIRECTORYID. If you check your web site (e.g., http://www.wam.umd.edu/~YOURDIRECTORYID) and you see "Index of ..." and a list of files/directories then you do not have a wam web page. Look at how my web page looks like: http://www.wam.umd.edu/~nelsonp. By the way, in the wam system your web page can be named Welcome.html rather than index.html, however use index.html.

This is a great Editor. It is free, and it works in both PC and Macs. If you are a Mac user I would definitively encourage you to use it. PC users should be fine with PHP Publisher, although give Komodo a try. Make sure
