Due to difficult financial circumstances I was going to establish paid access to some of my works. However, this would be unfair towards those also experiencing lack of money. For this reason I have decided to keep the resources free. Everybody who wants support the author can now donate any sum of money to my PayPal account. My account name is firstname.lastname@example.org. My name in PayPal is Anna Askarova.
You can also purchase this work for commercial use for 5$. This will allow you not to include the link to my website.
