Setting up and customizing the rules for your forum is easily done by going to the following area:
AdminCP >> Edit >> Inserts
Rules Insert Section
This is the Rules insert section where you can modify the content. Please be aware that the forum rules text is inserted directly into the HTML page. If you want to use a special formatting to set off part of your text, you will need to use HTML tags to do so.
After you've inputted your rules to your satisfaction, click the Update the Rules button to submit your changes.
