Well ..my last idea this night

Every existing site have two links in the footer

Example :

You wan't to help us ? Discuss and improve this site here (english only) - Report translation errors of this site here (dutch)


Every NOT existing or unfinished site ( especially the advanced tutorials) have this note in the english site :


You wan't to help us ? Discuss and improve this site here (english only)


Well, i know we can show the discussion tab in the wiki as well. But the board is much better to create and develop content.
