When viewing an editable page, you can select the “Edit This Page” option on the right menu. This will bring up a simple text editor where you can make your changes. Text can be formatted with bold, italics, links, emoticons, etc. using simple syntax. This syntax is explained on the right side of the text editor, and you can preview your changes at any time during the editing process.
Your changes will be attributed to your IP address and a “display name” that you are encouraged to fill out (on the right side of the text editor).
