I read on Talbot's Forums that he (or she) works on this fine plugin every now and then depending on free time.
I wonder why WordPress developers have not decided to incorporate this multilingual feature in the heart of WP system. If there is one feature needed, it has to be this one.
That being said, would anybody know when Gengo for WP 2.3 will be available? Are there coders other than Talbot working on this?
