I can see a few of them:
- js.too_few_topics_and_posts_notice
- js.too_few_topics_notice
- js.too_few_posts_notice
All of them have 3 to 5 placeholders for numbers, and each one needs pluralization. Having 4 variations for every number (one, few, many, other), total number of combinations is 12 to 20 strings, which might be not the best approach to translate this long message.
I suggest we split it into shorter pieces, each one having only one number placeholder, and pluralize each piece (one, few, many, other).
