Is someone already working on the romanian version of the lang file for 1.5.3?
as far as i can see, no.
You're welcome to do the romanian translation and share it with the community ;)
please read the translator documentation section in the docs before http://documentation.coppermine-gallery.net/en/translation.htm (http://documentation.coppermine-gallery.net/en/translation.htm)
Maybe I'll do that when I have time available... Any help would be welcome. ;)
