You are also a user at Stack Overflow, so I suggest you try following the steps of Stack Overflow's question [guided mode](https://stackoverflow.com/questions/ask). This step-by-step wizard will guide you through the steps of asking a good question. There is a lot of overflow between how to ask a good question at Stack Overflow and at Ask Ubuntu too.  

When it comes to writing a good answer, I also had problems when I started out at ubuntuforums.org and one of my answers was even deleted. It took 9 years for me to figure out why this answer was deleted, which I found out by means of an exchange of comments at Super User Q&A. By the time I started at Ask Ubuntu I was already a bit familiar with how these help sites work. In all these years nothing helped me to improve my answers as much as studying the criticism I received and trying to learn lessons from it.
