To be able to provide both PHP4 and PHP5 on shared computers, they have decided that PHP4 will be available on port 80 (standard HTTP port) and PHP5 on port 81. Since MediaWiki requires PHP5, all access are done through port 81 on the wiki. I have added a .htaccess file (contents below) to automatically redirect request on port 80 to port 81, so that people accessing the wiki without specifying the port will still have access to the wiki.

So what's this port 81 thing? leaving that off changes it to the standard http port 80; I don't know of any system that allows you to use port 81 if port 80 is the right port.

I'm at the University of Kentucky College of Pharmacy working with Chang-Guo Zhan, a physical chemist. The group does structure based drug design. Thanks for the suggestions about navigating through the cavities as well as the description of how to make the pdb animations.
