Becky, you have said that you don't know what necroposting is, so you might not know much about other forum guidelines, either. Here are a few tips, from experience
A) If you see a topic you want to contribute to, before you post, make sure the topic isn't too old. It will usually be old because it was derailed, or something similar.
B) If you have questions, don't post a series of topics about them. If they are that pressing, hop online and ask someone or PM a staff member, or indeed a regular player who might have the answers.
C) Think before you post/speak. You might already know the answer to your question, or you could use your common sense to answer it.
D) Be calm and factual when posting reports or appeals. Don't get mad at the staff if they can't help. Try to see from different perspectives.
Hope I helped
