Wikis are open source, right? I like the organization setup of wikis, and am thinking about making one. I would like to have an encyclopedic resource for my fictional world, and a wiki is a great resource to do that with, but I would be unable to do such a thing on Wikipedia as it would be advertising. That being said, I have a few questions...
1. Is it relatively easy to set up a wiki? Do I have to understand PHP or any complex coding to set it up?
2. Can I lock other users from contributing unless I give explicit permission... I know most non wikipedia wikis are fansites, and this may be viewed as vain on my part, but I want a wiki for ease of use for Cross-referencing, and that's the only reason I want it to be a wiki over a plain website. It is much easier to type [[ article in question ]] than it is to type "<a href="www.whatever.com/articles/article_in_question">article in quesion</a>"
