You can see it running on
PhotoPostDev.Com; its basically PhotoPost integrated with many of the nifty new vB3 features like expand/collapse categories (compatible with vB side), vB markup code/smilies in comments/posts/signatures, enhanced/WYSIWYG editors for comment posting and quick replies, etc. Of course we already integrated with vB stylesheets so they are automatically picked up and with signatures/avatars.
