I have started to translate some wiki articles to Hungarian (I know the babelfish competition has ended but it is for sake of the community :)) and I try to follow the the guidelines in the WikiHelp article:
bq. If you translated a wiki page keep in mind that it has to be accessible from existing language versions.
And this is really a painful exercise on those pages which were already translated to several languages (like WikiHome). As the community grows and new and new languages will appear on the site it will become almost impossible to manage it. Did I just overlook a feature which solves this issue or this manual solution is the only one? If later, I would like to suggest to somehow automate this process (eg. let people register the translated page and prepare the language navigation bar automatically).
