Hi! Is possible to translate BOINCstats/BAM! to Galician? If it is, I would like to do it myself. Where can I find the language files?

There are no language files but an online translation tool delivered by Willy to us volunteer translators.
I dunno whether he already contacted you by pm, but this is the goal:
1022 words and small phrases
255 country names
22 days and month
56 project infos (just short sentences)
57 BAM! info phrases
31 BAM! errors
66 FAQ Q'n'A, sometimes quite elaborate

But imho it's fun, I like it for german. You should probably come up with a copylefted flag symbol as well, I dunno whether it's so common knowledge.

Well, it seems quite easy, and I enjoy translating. About the flag, it's so simple that I can do it myself with copyleft.

Thanks for the info, I'll wait for Willy to reply or to send me a pm.
