All my apologies for the forum interruption. We suffered a slight technical problem, but unfortunately I wasn't able to solve it at 2am last night, so I did it this morning. (took over 2h).
I suppose this happens because we are not using the final version of vBulletin 3. As soon as it is released (in a few weeks ?), things will be smoother and we will reinstall the custom options such as the country flags, quizzes, etc.
Please be patient. We are also working on a new article section on JREF.
