I'm sorry I confused you, Nathalie. When you filled out your profile, you checked a box that said you did not want any of the CatSite members to be able to reach you personally by e-mail. That means if I want to tell you something that I don't want anyone else to read I cannot send you a personal e-mail. That's all it means. It protects your privacy. A member can send you a private message, which stays here, but not an e-mail.
Separate from a personal email is notification that someone has responded to a thread, or subject in which you have shown interest. Let's say you have a problem with your cat's behavior, and you need advice. You would start a new thread (a subject-with your name on it) asking your question, and hope to get replies-(posts). Every time someone replied the computer would automatically tell you that someone had replied to your personal problem. You would welcome that notification, and would come to the CatSite to get each new answer. So far, this is only the second answer you have received, and you needed more than one to clarify the answer, so you're probably glad I answered again. Sometimes people get only one answer; sometimes, if the question is controversial or very interesting to almost everyone, twenty to 100 people might answer!
If you reply to someone else's question, you are subscribing to his thread. If you lose interest in that subject, just click the line which says you wish to unsubscribe to that thread (separate subject). You will no longer be notified of new replies.
The alphabet game is not a problem that someone needs to solve; it's just a fun pass-time for us. Many more people answer, because it takes only a minute, and your answer can be one word. Therefore, you will get notified every time someone comes up with a new answer. If you do not want to be notified, click the "unsubscribe" line. Unfortunately, if you play again, the computer will again start notifying you of each answer. You will have to click "unsubscribe" to the first notification you receive every time you have added a word to the game. Or, do what I do. Let these particular notifications pile up; open the most recent one, and just delete all the other alphabet game notifications. I hope I was more clear this time!
