Welcome to this session! For the whole day I'll be looking at the replies to this thread and answer your questions. If something remains unanswered, replies can be posted even during the following days.

There are no rules, "anything" is anything! Use a grain of salt and a little bit of irony, though. Also, I would really like to hear something in your native language on your first comment: it can be a greeting, the question itself, a joke, an insult or anything crosses your mind in that moment. Have fun!
