I want to start a wiki for group knowledge-sharing at work. I'm not a manager, so I can't set aside a special (virtual or actual) server; and on the server where I can run it - I might not even have root access. Also, it has to be flexible in the sense of not being picky about what's available on the system, and being easy to "pack up" and migrate to another machine as necessary with minimum hassle.
The wiki will likely not have incredibly fancy and complex programmed elements; also, I'm not experienced with Wiki systems as an admin - only as a user (and not even such a power user).
The wiki has to be FOSS, or at least gratis for both commercial and personal use. Also, it should (somewhat) actively maintained.
The material may include a bunch of text, some formal math, occasional tables, scans, diagrmas... perhaps a short video.
- I'll be choosing and running the web server, so you can make assumptions about it if necessary.
