We now have a dedicated section to tutorials. They can be found here,
in the download section.
If you are uploading a tutorial, and it is for specific software, please name it appropriatly. I.e. Photoshop Shape Tutorial, or PSP Colour tutorial. Unless it is a universal tutorial such as Monitor calibration tutorial.
Please also respect the original author. Do your best to find who made the tutorial, and give them their credit.
