I'm an active member of the ELL community because explaining why something is said the way it is in English is a great way to learn advanced grammar, which I was never formally taught.
Helping folks learn English has been a great tool for my own studies in French, and learning what it's like to be a student in another language has helped me better understand the perspectives of people here who are learning English.
Keep practicing, keep asking questions, never stop learning.
