K say you want a page called about us.
Make a template in lets say skin1/help since that is where current versions have their templates like this.
call this template aboutus.tpl put your table tag in the file.
Now add this to index.tpl in the skin1/help folder:
{elseif $section eq "aboutus"}
{include file="help/aboutus.tpl"}
So now add a button somewhere where you want them to click on to go to the about us page.
So the link would be.
About Us
This would keep the page to pop up into the main page of your website. If you dont want it to do that and to pop up on its own then just have it link to an html file and put a _blank target in the link tag.
Hope I didnt forget anything, been awhile since I did this.
