Our site: http://do4a.com/ We had vBulletin based forum and livestreet (WP alternative) based blogging system. Yesterday we imported all the content to XenForo. I used vb4 importer for forum and had to write own importer for blogging system. The site uses custom addon which has News, Blogs and Widgets. The addon was coded by me together with Yoskaldyr and templated by CyberAP. We are very glad switching on XenForo. Coding for XF is a great pleasure. Yesterday the site handled 700 online users on 20$ shared hosting without Zend Cache. Very thank to developers Kier and Mike!
