Hi there, i'm new here. And I have a few questions: For a while, I had Paint Shop Pro.. and I loved to make blends and stuff. So my questions are.. can you make blends with Paint.net? Add brushes and stuff? And if you can, how do you do that? Another question: Is paint.net free? Or do you get just a free trial? Hope to get an answer soon. xx
