I need to create a wiki with some specific characteristics:
- User accounts required which can have varied access (basically, view or edit)
- Has to be modifyable, since some features are needed that I can easily write, but that wouldn't generally be included
- Fairly user friendly and intuitive, especially to edit, since the guy who'll be using this isn't really a computer guy. Doesn't require really difficult code.

If nothing else, I'm going to try out mediawiki, although I'm not sure what kind of user account access it allows. I figured I'd ask here first, just in case somebody else has experience with this.

If you know Python (it's easy), and don't mind getting used to the Django framework (it's very awesome), then you can use one of these two wiki applications written with Django..

Since all Django applications are just Python modules, you can easily only use the Wiki software provided by both.

Hmm, I don't know Python or how to use Django. That sounds handy, but I'd really prefer this to be a quick project, I don't really want to spent a lot of time or learn anything.

I have used MediaWiki and have one running, will give you an account to play around as admin and see how you like it.

Thanks, I appreciate it, but I am actually running a MediaWiki right now. I haven't looked at the administration or user accounts at all, though, but since you recommend it I'll definitely have a closer look.

Thanks!
