How can I be notified of KudoZ questions in other language pairs?

To be notified of questions asked in language pairs you do not want to list as working language pairs in your profile, just report the language pairs in question as interest language pairs.

To do so, go to your Profile Updater and report your 'non-working' language pairs in the Languages section.

Once reported, click on Edit next to each language pair just added and select I only have an interest in this pair, do not show it in my profile. Remember to save all the changes you apply.

Finally, go to your KudoZ dashboard and set your KudoZ notifications preferences for these language pairs as you have done for your working language pairs.
