We have a PHPNuke site which we need to be converted to another CMS. The options are Mambo/Joomla or ezPublish (if you are an EXPERT with another open source PHP CMS then please suggest it). The following data needs to be converted from the PHPNuke site: Users Polls Articles PHPBB2 Forums and Posts Modifications have been made to PHPNuke to require additional information from the users. These modifications will need to be in the new CMS. You will need to implement a theme (include company logo and colors) as well.
