* **For a general site promoting the value of continuous improvement of grammar**, option 2 should work.

**Key considerations for the description:**

* **Clarity:** Make the meaning of the tag clear.
* **Relevance:** Accurately reflects what the tag is used for.
* **Conciseness:** Keep it brief without sacrificing understanding.
