I created the Translation Links module as a way of making translations of nodes easily accessible on partially translated multi-lingual websites. Such websites will have Drupal 6 core's Content Translation module enabled, but not many or perhaps any of i18n and it's modules that enable multi-lingual features for menus, views and taxonomy.

It achieves this by creating links to translations in convenient places, such as next to teaser titles, and as local tasks (aka tabs) on node view and edit pages. It's a fairly simple module, yet highly useful for such websites.

I have created an RC release for testing. The module doesn't do any writing to the database so can not corrupt data. Please try it out if you are working on such a semi-multilingual site and let me know if it's useful, works, breaks or provide suggestions for improvements on the issue queue.
