If you write a tutorial, please indicate in your post what software is used in your tutorial. This applies to any kind of tutorial post, whether the body of the tutorial is included here or the tutorial is elsewhere and linked to here. If your tutorial is posted here in its entirety, please include the software information before the cut. This will aid people in determining whether or not they want to follow up on your tutorial.
And since it never hurts to reiterate, please indicate what software you use when you ask a question as well. This helps commenters tailor their answers.
