 * Enable IPv6 support (the domain has it, I just need to program the backend to

-* Add internal page hit counters so I can gauge the popularity of pages.
-  connections to the webserver for analytical purposes.
 * Add links/descriptions to all of my old and current projects.
 * Add a page about me, which includes what I am a member of, what I value, and
 a list of the organizations that I contribute to.
