In Drupal 7, it's possible to add context to strings, to make it possible to translate the same string in different ways. (More info: http://drupal.org/update/modules/6/7#locale_context )
I've just opened an issue for adding context to "Strong", which needs to be translated in two different ways for Norwegian. Since other languages may have other needs for that string for all I know, I'm posting this alert here, so others can join the discussion. I'll also send an email on the translation mailing list.
The issue is here: http://drupal.org/node/950028
I added the issue tag "string context", please add the same tag if/when you open issues about adding other string contexts. I don't know if it would make sense to post alerts about future such issues here, or maybe collect them in a handbook page somewhere.
Important: All comments about that specific string need to be in that issue, not here!
