I want to share a 7 min. video of users interacting with the initial implementation of the language selector:

http://www.youtube.com/watch?v=ZbUhuAvyPr4

The video includes fragments from the users that agree to make it public their participation in the latest round of tests. 
This round was based on the implementation available at http://translatewiki.net (and not interactive prototypes as in previous rounds).

Since Google Hangout was used for the recordings, the video quality is very low. Nevertheless, making this public may help to make visible to the community 
that users are in the center of our design process, and encourage their participation in future usability testing sessions.
