@vIosOnE: I always forget about the languages. I haven't generated the files for a while, so there are a lot more missing that that. Any chance of doing the rest?
I have attached the updated es.po file as a zip file. You can edit this manually, but a good tool is
POEdit. It a free tool that opens the PO files and lets you do the translations. The untranslated strings will be in bold.
And if anyone want to do other any languages, that would be appreciated. If you do, post the translated file here.
