I have postnuke website version 0.7.5.0. with large Community Users,Forums,Article, Gallery in 3 languages(English,Germn,Persian) I would like it to be converted to Joomla 1.5.2 Component using Joomla standard development practices. Thies are to Convert * All the Users must migrate to joomla. * PNphpBB2 forum must work properly and all forum posts must be migrated to Joomla - All articles - Gallery - Selecting the languages Payment will be fully made when the module is fully functional on my Joomla site. There are several other improvements that i would like to do but we will make them as add on's later and we will agree on how much it would cost like the following: - Improve the users functions - improve the admin functions. ...etc The current PostNuke module can be viewed at [login to view URL]
