jSeblod CCK - a very powerful component - content designer for Joomla. Write what or annotation for this extension is useless, the link below have enough information to enter into the subject, from myself I can only add that this entry will not be fast, so I recommend the local server to deliver fresh Jumla and install the train. But if you have enough patience to master this car - you will not get Jumla completely different engine, with other features. This distribution is not intended to update earlier versions - only for new installations. Patches for updates, you can take on the developer's site. License - for free. Russian language in the archive - set as usual extension.
