At the drawings section in the top where it says hme, tut, drawings? Well click on drawings if you want to draw there and add a drawing in the white menue.
If you want to create a tutorial just add it at the tutorials section, it can be featured if you're good enough! :D Or you can create a drawing or tutorial at you account with these two HUGE buttons that says "create drawings" or "create tutorials"
Hope it helps! Welcome to this site
