the ground-up over several months to introduce some truly unique features &  
performance enhancements."  
  
"The new administrator control panel now offers the most comprehensive  
control panel available for any ASP.NET based forum today. Advanced  
security features such as role based permissions and our unique Permission  
Sets feature provides unparalleled configurable control over the content  
and features that are available to your users within the forum. Moderators  
can easily be assigned to specific forums with dedicated moderator  
privileges for each forum. Bulk moderation options ensure even the busiest  
forums can be managed effectively by your moderators."

unique layout or visual appearance. A single central style sheet controls  
every aspect of a skins appearance. The use of unique HTML wrappers and  
ASP.NET 1.1 master pages ensures page designers can easily integrate an
