there was one problem with my browser, konqueror, some fields had another translated string with that i saw in the translation extension of the wiki. With firefox i saw the "real" translations.
After that the link : :
and it is marked as red (unexisting page) Is this a problem ?
I did nt understant what i have to do with the "Categories" as i cannot translate the equivalent English page. I think that the page "http://userbase.kde.org/index.php?title=Category:Για_να_ξεκινήσετε/el " will be composed with subcategories automaticaly, so it is an autogenerated page (?) or i have to add a text here : http://userbase.kde.org/index.php?title=Category:%CE%93%CE%B9%CE%B1_%CE%BD%CE%B1_%CE%BE%CE%B5%CE%BA%CE%B9%CE%BD%CE%AE%CF%83%CE%B5%CF%84%CE%B5/el&action=edit&redlink=1
Sorry, i am a little confused with this point.
