Oups sorry for not replying. I think we should change the wiki text as we simply have no time to track those emails.
Of course, if you want to put time into translation then hell yeah. But you should then consider taking care of the translations also after you're done as texts tend to change over time so its a sort of commitment to keep stuff up to date etc (eg. we are slowly working on re-writting about page). We hang out at firstname.lastname@example.org (if you use jabber/xmpp client) or via webchat so you can coordinate with us and other disrooters that do translations and write howtos
