New to Wiki?
The Easiest way to get started with wiki is to look at what people have already done. Go to a Random Page and click the "edit" button at the top. Make youself familiar with the way content is entered into pages.
The most important idea behind editing wikis is Dont be afraid of editing! Don't worry if what you add doesn't seem formatted correctly or if you are unsure what to do. Someone else will come along and fix it up eventually.
refer to Wikipedia's "How to edit?"
Word2Wiki is a MS Word Macro that can convert Word formatting to wiki markup.
