LOOK AT THE STICKY THREADS IF YOU ARE NEW TO A PARTICULAR FORUM

Sticky threads are those that remain at the top of the forum. They have been "stuck there" because the moderator (someone like me) felt that they contained especially good information or that they addressed a frequently asked question.

In most cases you can post to the sticky threads so feel free to ask questions that relate to the topic of the thread. Even if the thread was started 5 years ago the information is still believed to be useful and relevant and the people in the thread will be a good source of information.

Stay on topic. If the topic of the thread is "what is the best beginner airplane". This is not a good place to post questions about how to fix your helicopter. Try to post questions or comments that are related to the topic. Otherwise you are going to annoy some people and really anger others.

If you ask for help, and the help offered resolves the problem, post the result and thank the people who helped you. It will create a lot of good will. It will also make that thread valuable to others who have a similar problem. They will see the recommendations and they will know what one worked for you.
