Hi Pawan,
Welcome on board.
I would like to add nepali translation..
It will be a pleasure having a Nepali translator.
Please advice how do i post po file.
The best method is to zip your ne.po file, and attach the compressed file in a new patch. See the patch tracker: https://sourceforge.net/tracker/?group_id=93438&atid=604308 But it looks like, you're already aware of it.
Another suggestion is taking a look at the translation information page on the wiki (if you've not done so already): http://wiki.inkscape.org/wiki/index.php/Translation_information
thanks,
Thanks and regards,
matiphas
PS: i will be away this we, and thus won't be able to check/commit your patch before monday, but maybe someone else will be able to do so. Once again, thank you very much, and welcome
