It's been a week since I had visited Wikipedia due to my business trip. It looks like a lot happened during this time. The first thing I saw was that I was or am under a topic ban which I believe absolutely unjustified, and that some of my fellow Wikipedia editors worked for me and left me valuable advice. (and, without a doubt, some editors who have been hostile to me did a lot of things to bury me.) 
 I guess I have many things to do from now on. First, let me thank to my friends and apologize to them for my absence which may have caused them unnecessary trouble. Second, I will thoroughly examine what happened during my absence, making appropriate replies to all messages to me. And finally, I will take care of this topic ban issue and come back to discussions which I was involved in, debating harder than before, probably.
