Sorry, I realize this isn't a travel related website. However, having been an Italki user for a while, I feel like for the most part the people on this site seem generally inclined to be helpful, and part of a learning a language is learning about how a society or culture is put together. I figured that it couldn't hurt to ask. Most of my questions are directly about language, with the admitted exception of a polar bear related question I recently asked. In any case, thanks for the information!
