I wonder why no one has sent me any messages regarding my edits! If those edits have violated Wikipedia guidelines, I would like to know about that! Also, why have I not received any notices whatsoever about how to use Wikipedia? I can see that all of the other users have received notices of some kind! What about me? I cannot get any answers from the Wikipedia chat room! Some of my questions don't even appear! How do you change your watchlist? How do I add my name to a WikiProject?
