Translation Tips and Modules for Multilingual Drupal sites
Drupal has some excellent translation functions but deciding which modules to use and how to configure the modules is challenging. There are many different possible configurations depending on your website needs, domain names and content. You'll find there are a lot of choices of modules for setting up a multilingual site.... then there are a lot of key configuration items to enable depending on your website.
This post focused on Drupal 6 modules and issues. We will give some example of the difficult decision making involved in translating content. There is no out-of-the-box configuration that seems to work, it all depends on the needs of your website. There are many different modules to choose from in core and contrib and a lot of their functions overlap.
The best advice is to start with the core multilingual modules and then add other modules when needed. Good Luck Bon Chance Viel Glueck 幸運 Buona fortuna 好运 Buena suerte Удача

Translation issues and quirks with Drupal
Blocks of custom menus must be duplicated. When you create a new page with a menu item, then translate this page, the menu item does not automatically translate. To do so, you must specify a new menu item for the new page - not difficult, but something you should be aware of.
Custom made menu items are language independent. These items are not automatically translated when you change languages, thus you must define a menu item for each language (ie: en/node/add/page, fr/node/add/page)
Since VIEWS cannot translated, this create a number of issues for blocks. Specifically the built-in block for blogs, 'Recent blog posts', will show up on the base language, but not the others. The solution is to create or clone a view with a block, then in your Multilingual settings choose the new language. The nice thing about this solution, is that it allows you to create a new view with translated title, fields, etc... You can also consider installing the i18n views integration module module: http://drupal.org/project/insert_view
Important Admin Pages
Start with the Translate interface. This page imports the translated strings contained in an individual Gettext Portable Object (.po) file. Normally distributed as part of a translation package your.domain/admin/build/translate/import This string search page allows a translator to search for specific translated and untranslated strings, and is used when creating or editing translations: your.domain/admin/build/translate/search
