What language use in my notebook
I am brazilian, I'm learning Arabic, and I want to write what I'm learning in my italki notebook. It would be more comfortable to write in Portuguese, but since I'm think those annotations are public to people comment and correct me, and I'm not sure there are much Brazilians learning Arabic, maybe it's would be more useful to write in English, even I not being fluent in that language too.
What is better?
