I have just downloaded latest SVN from http://n2cms.googlecode.com/svn/trunk/ and compiled it in Visual Studio 2008
AND IT WORKS WITH COMMENTS !!!!!! GREAT!!!!! It was the only thing which official versio lack for me.
THANKS FOR THIS GREAT CMS, IT IS DEFINITELY THE BEST CMS FOR ASP.NET
(much better than Cuyahoga, mojoPortal, DotNetNuke or BlogEngine.Net :-)) )
