I know that some Example tags could be shown when trying to post a question. But my query about if the person didn't coose any of the Example tags, could any of the Example tags be attached automatically with the question in this situation.
You can do this by modifying function qa_question_create(...) in qa-app-post-create.php - check if $tagstring is empty, and if so, set it to whatever you want, using commas to separate the tags.
