I have installed some old version v.2.0.1.0b SEF from fantastico. Using fantastico was bad idea, but everything is working fine now (thanks to Dewed).

Translated in about 80% at the moment, no additional skins or modules. I want to use Joomla! bridge and buy suitable domain, but translation is more important for me right now.

If somebody wants translated files, please contact me by mail - biuro[at]mtti.pl (short & simple messages please - my spam filter is a scaremonger )

================
Everything is translated now - fronside and admin section. Not everything is inside language file, so there is no possibility to completely switch back to english.
Simple logo has been added and new theme based on 'original' theme (temporarily - I'm counting for some modern-looking theme). Next checkpoints are: new categories schema, new domain (subdomain katalog.mtti.pl) and google ads.
