After a few false starts I've started up my own personal wiki. In the end I decided that MoinMoin would be the best choice for me, since it is fairly small and simple. TikiWiki was interesting, but just way too much for a small personal wiki. Now I just need to make some themes. to make it fit in with the rest of my site. Anyways, you can get there via the link on the left, or by clicking here.
There really isn't that much in there yet. But I'm planning to use it for random information I want to keep track of. And if you want to contribute at all just let me know (everyone has read permission unless I grant them more).
