Video that explains how a wiki works.
A wiki is a website that allows everyone who has a browser and Internet access not only to read content but also to create new pages and edit every page freely. Acts of vandalism can be reverted as every page preserves a history of past versions.
The best known wiki as of today is Wikipedia, a free encyclopedia in more than 200 languages that already features more than 3,700,000 articles on all kinds of topics in the english language version alone. If you want basic information on anything, Wikipedia is a recommendable, perhaps the best, place to go.
For that reason, probably the best description of what a wiki is and how it works is the article "Wiki" on Wikipedia. See the link at the bottom of this page.
You are currently on the Spanking Art wiki, so you can edit any page you like right away. Just use the "edit" button on the top of the page you'd like to edit, then make your edit, preview it and when you're happy with how it looks, save the page. Your changes will be immediately visible - to everyone. We trust you will not do nonsense here, but use this privilege responsibly to improve the wiki. If you see a red link on a topic you'd like to create an article on, just click it and you'll get to an edit box where you can enter content. There is a special syntax for formatting but it is pretty easy to learn. To get started, see the links on the Help page.
If you're new to wikis, a good idea is to have a look at the source text of any article by just pressing the "edit" link but not saving the page afterwards. This is also useful to copy and paste wiki source.
