I don't know where to post it, i'm italian and ready to translate the last release in italian. Is this the right place to post?
This isn't really the good place ;)
To translate, check http://gitorious.org/geeqie/geeqie/blobs/master/po/README
For italian, the best is to clone current master tree, and update it.po, then you can use a merge request on Gitorious.
Else just attach the new it.po here i will commit it
