Help:Editing
From Sjcs2000
Here are some guides that will help you start working. Please read through all of them for you to familiarize with the WIKI style.
Also don't forget to place a summary of what you have edited in the Summary text box provided. This will give those who are checking the pages an idea of what you have added/removed from the specific page that was edited.
Also check the minor edit checkbox if you are editing something minor (eg. typographical errors). I leave to your discretion what is a minor edit or not.
