Although made specifically for Wikipedia it can be used outside a wiki context.
Updating an existing timeline (e.g. correcting or adding an event) should be easy indeed for uninitiated, yet creating an original design and fine-tuning may easily take a couple of hours. I'm not sure everyone would consider that 'wikiwiki' enough. :)
Once I got some new features online, and unicode support added, I will work on more examples, which can serve as a template.

Here are two great sites that may serve as inspiration, my hands itch to recreate some of those timelines verbatim, but I'm afraid that would be 'not done'.
Hyperhistory (e.g. click on button 'people' left, then on 'special lifelines', right. http://www.hyperhistory.com/online_n2/History_n2/a.html
I hope we will have a set like this in a years time (click on full size image for any map), possibly even with images. The main effort will be to gather all info without snatching everything from here (most of these maps are based exclusively on data from Brittanica). http://chaos1.hypermart.net/pg/world.html
