Be polite. Even if you don't agree with people. If you see someone misbehaving, use the report tab. Answer questions to the best of your ability. Do NOT answer with, IDK or google. Ask fun questions that make other users use their brains. Follow people you find interesting. Give "helpful" stars to those of us who take the time to answer your questions. Have fun.
Once you get addicted, you may have to give yourself "timeouts" so you can like, pursue a real life, even if that means heading down to a local bar and interacting with people without an "electronic curtain" between you and the folks you interact with. ALSO...DO NOT under any circumstances wonder why some of your questions, answers, and comments get pulled, by the moderators. Some mysteries of the Universe just need to remain mysteries. Welcome aboard.
Welcome, Lui, to our Ask family, honey! You've already received some really great advice from the others on here. Really, just be as helpful as you possibly can to people who ask questions. Don't bother to answer questions you don't know the answers to. As someone else said, some will answer with "I don't know." Don't answer a question with, "Why would you ask a question like that?" Yep, seen that one, too! Just by the way you've asked your question, it's evident you're a very polite and caring person. So just be yourself. And when someone takes the time to thank you for your answer, always take the time to thank them back. You're going to do just great, darlin'! Hope you really enjoy this, Lui. And, again. welcome!
