Posts in multiple languages are still not easily made under wordpress! Some tries were made with Polyglott and Language Picker but it’s not possible without mingle around in code. I wished there was a plugin or widget which could do it… A normal user won’t want to read thru lots of howtos or blogs which tell him to change code in that and that file! He well have trouble to update to a new version of WP later. I’m a german web-designer living in Turkey, can think in three languages and would like to write my blog in three languages too – without having to open three different sites or databases.
Another multilingual plugin I tried out recently is Gengo… but… No! The concept looks actually quite promising but unfortunately it is not stable. Development and support seem to be frozen for months… conflicts with other plugins can occur… No!
Update – after 2 years waiting :
Finally there’s a very promising plugin called WPML – I can say: yes! It works. It still has some bugs but it is under steady development…
