It was ok yesterday, but today when I click on the 'help us' internal link ('According to your profile information, you can help us in evaluating some translations. Help us'), the website is not selecting any languages; instead, it shows all translations being evaluated, in any language. The link via 'translation' -> 'translations to be evaluated' is working.
, it has been corrected now. It was because of this : http://www.cucumis.org/forum_1_f/read_rs_0_2543.html
