How can forum users avoid repeating questions and contribute positively to discussions?

To avoid repeating questions on forums and contribute positively to discussions, users should first search the forum for similar questions before posting. They should also read through existing responses to see if their question has already been answered. Additionally, users can add value to discussions by providing helpful insights, sharing relevant experiences, and offering solutions to others' questions. 

// Example PHP code snippet to check for duplicate questions before posting
if($question != null) {
   $existingQuestions = $forum->searchQuestions($question);
   
   if(count($existingQuestions) > 0) {
      echo "This question has already been asked. Please check existing responses before posting.";
   } else {
      $forum->postQuestion($question);
   }
}
