Because of the fact that no real work with getting JoomFish for Joomla 2.5 working is being done, DT Register now has no solution for implementing multi-lingual dynamic contents. Nothing much has been done for JoomFish development the last year, it is impossible to get in contact with the guys behind JF and there is no working version for J2.5 or roadmap for when and how it will be made ready. A pre-alpha J-future release has been sitting for half a year with loads of bugs and undeveloped parts.
Therefore I am very pessimistic regarding the future for JoomFish, and I think it would be very good if you guys at DTH would create content element files for use with FaLang which is rapidly being developed and already works well with J2.5.
