Try this for your css:

<style type="text/css">
strong {font-weight:bold;}
ul.unordered li {list-style-type: disc;list-style-position:inside; display: list-item; margin-left: 2.5em; padding-left: 0;}

ul.unordered ul li {list-style-type: circle; display: list-item;margin-left: 2.5em; padding-left: 0;}
</style>

And you aren't nesting them correctly. The <li></li> needs to be around the nested list, ie:

<LI>SubForum under the Sponsor Section 
  <UL> 
  <LI>The sub forum allows sponsors to post specific company information, deals, specials, new products, etc that you want to advertise.</LI> 
  </UL>
</LI>
