 FAQ:
   - How do I add, change, or remove a string?
       Just update this file.
   - Translations will happen automatically??
       Yes, indeed. Just add your string before the branch point and
       make the description good.

Translators probably need more context here. What is the "interests button"? You
should also contact the l10n team to make sure they've added "Interests" to
their translation glossary.

Don't need CHAR-LIMIT. CHAR-LIMITs should only be used if a long translation
will be truncated or break the UI. See the top of this file for more details on
CHAR-LIMITS.

Done.
