Its not only the "tutorias". Its the quality of the posts itself. They provide no information, or wrong information. Your posting way faster and more that Dark Raider is (which is really hard todo) with the difference that Dark's posts are interesting and the information provided is true. No need to apologize, just cut down on the amount of posts you make, and increase the quality. If you have the feeling that writing a tutorial will take you days (like you have said in one of your posts), then take your time and write it locally on your computer somewhere, and post it at a later time when its complete.

Good luck to you.

Cheers.
