How do I enter "languages of interest"?

To enter a language of interest in your profile, just enter a new language pair from the "Languages" section of your Profile updater as you would normally do (following the steps described here). Once the language pair has been reported, click on "Edit" next to the pair just added and you will be given 2 options: 1) I work in this pair, show it in my profileand 2) I only have an interest in this pair, do not show it in my profile. Select this last option and finally click on 'Save and update profile' at the bottom of the page to save the changes applied.

If you want to turn a working language pair into a pair of interest, just go to the "Languages" section of your Profile updater and click on "Edit" next to the language pair you want to change. You will be given 2 options: 1) I work in this pair, show it in my profile and 2) I only have an interest in this pair, do not show it in my profile. Select this last option and finally click on 'Save and update profile' at the bottom of the page to save the changes applied.
