Before posting a question, it is advised that you search the forum archives and product documentation first. This will help you to avoid asking a question that has been answered many times before.
Try to be as clear and detailed as possible. Usually, including an example patch that demonstrates the question is very helpful. By taking the time to formulate your question, you will greatly increase your chances of getting it answered.
Be courteous and respectful of the community. As with any online forum, it is advisable to spend some time "lurking" before jumping into discussions.
