Talking with tomaslucas, we both spanish speakers, agree that is important to have the wiki documentacion translated as soon as possible according to the languages the system is able to show.
That's because when you read, for exemple "The 'overview' page", in spanish the page is called "General"... and well... if we're translating tha app.... is obvious the need to traslate its documentation, is't not?
Well... perhaps, the firsts steps in that way were be to provide teh users, from the wiki main page, diferent language options. I supose the wiki pages will be created "on the go", or a simple copy of the english version, to begin with, could be a great help.
Then, every one can collaborate with him/her own language wiki pages... Is there anybody ready to begin work translating the wiki? Me, at least, to spanish.
