Thanks, it is already available in the CVS. I just forgot to answer your
first post.

Yes, I noticed Norwegian bokmål was added yesterday, but this is the Norwegian nynorsk translation :-)

Norwegian bokmål (nb_NO - or short version nb)

Norwegian nynorsk (nn_NO - or short version nn)
http://orsta.org/i18n/roundcube-translation-nn_NO.tar.gz

We have two official languanges in Norway, and the above is a translation for both of them. As mentioned in a previous post, the "default" tends to be nb_NO, so language code 'no' og 'no_NO' is usually an alias of this one.

Thanks,
