Hello! I'm a lifelong English learner (non-native speaker), well, with some long;-) breaks. I speak North American English, and have just recently gotten interested in English dialects esp. North American ones.
I'm preparing for the Cambridge CPE exam; next, I'm going to take the Celta course. So aiming for depth and breadth hope justifies some of my questions that might bother you. I have not focused on grammar until recently, and as a nonnative English learner I hate prescriptive grammar.
If you spot a language MISTAKE, please CORRECT me, and if I sound UNNATURAL then ENLIGHTEN me. I don't feel offended out of good faith.
