multi-language

I have ordened the -to my opinion- most interesting candidates for further research here:
* http://wi-ca.org/Drupal_translation
* http://wi-ca.org/Drupal_multi_language

It's about selecting modules that possibly could serve most for a complex multi-language site. I've left out some modules in the pre-selection.
Yes, there should come a wiki for the translations group, but maybe in a different form than I did (as I for example already have left out some).
Then in that wiki some explanation why one should use this module for something and not the other one?

What is the current status of multi-language support in Quiz ?

According to [#285570] should be fixed. But when looking at the code in quiz.module in 6.x-3.4, I don't see any reference to language. So it seems that it was dropped in Quiz 3. In Quiz 4, language is only used when copying questions of a translated Quiz.

I'm specifically interested in random selection of questions using a taxonomy term. I'm working on a patch for Quiz 6.x-3.4 to handle multi-languages (ie. node's language) and i18ntaxonomy in _quiz_get_random_taxonomy_question_ids(). So I wonder if there is a ongoing effort for multi-languages support that I can join or if I should fill a new issue for this.

Here is my patched version of _quiz_get_random_taxonomy_question_ids().
