UK Blogger Phil Gyfford offers Chronicler to the world: ‘With Chronicler it’s simple to create, update and maintain your own archive of web pages such as a personal diary or journal, or even a daily magazine’. I haven’t tried it yet, but you might.

Update: tried it. Fairly simple to install but not as intuitive (or sophisticated) as Greymatter. Instructions are good but perhaps more details on file/directory permissions would be helpful.
