is the FREE collaborative editing software that runs Wikipedia. Requires PHP 5Software Santa's Note: This is BEST Used for Schools or Organizations that have an Intranet or a Web Server with PHP available to them. If you wish to install it on a single computer - and run it "locally" from the Web Browser of Choice on that one computer - you must go get and install XAMPP on that computer first.

What MediaWiki is...http://www.mediawiki.org/wiki/MediaWiki
MediaWiki is wiki software.
If you don't know what a wiki is, then please read this Wikipedia article before going any further!
MediaWiki is server software.
As with any software that you expose to the internet, there may be bugs or security problems. Do not install MediaWiki unless you intend to keep up with security upgrades (please subscribe to receive announcements of security updates).
MediaWiki is geared towards the needs of the Wikimedia projects.
The program was primarily developed to run on a large server farm for Wikipedia and its sister projects. Features, performance, configurability, ease-of-use, etc are often designed in this light; if your needs are radically different the software might not be appropriate for you.
MediaWiki is free software.
No guarantee or warranty of any kind is provided.
Try out Wikitext
Yes, you can easily modify pages and you can (temporarily) publish dummy sentences, and you can even (temporarily) completely destroy a page in a wiki. You don't need to have any programming skills to do this.
We suggest you exercise yourself within our sandbox. Please isolate your testing there, though: the admins might not take too kindly to your mischief otherwise.
You can also look up the cheat sheet which contains basic formatting commands.
Some things MediaWiki doesn't do so well...
Because MediaWiki was designed for open-content, it is often not suitable for situations where you want to restrict access to part of the wiki.
MediaWiki has been designed to serve very high-traffic websites such as Wikipedia. It has been optimized for this use and may not be so suitable for smaller sites, where disk space or memory are bigger restrictions than bandwidth.
MediaWiki is not normally a suitable replacement for dedicated forum/blogging software if that is what you are after.
In the above cases there may be other wiki software (or non-wiki software) which better serves your needs.
