As a result of switching to Typo for davidvg.com, I will no longer be maintaining 60cycleCMS. However, it will still be available on SourceForge at http://sourceforge.net/projects/sixtycyclecms/. If you really want to use, fork it, or whatever, go right ahead; the code is licensed under a BSD license.
Frankly, I wouldn’t recommend using it for new websites. I wrote it when I didn’t know too much about web development, and it’s quite possible that it’s vulnerable to a few hacks (see this post for a discussion of some of them). So, consider yourself warned.
I, for one, welcome our new Typo overlords :-).
