Plugin(s) and download(s) provided on http://www.fusedthought.com may be free and under GPL but much time and effort is needed to develop them.
It makes one motivated when somebody takes time to consider the value of the provided work. A simple email is greatly encouraging.
Of course, if you'll like to take a step further and donate, it'll be greatly appreciated as all donations would go into my education (college/university) fund.
I do hope my plugin(s) have helped in any way.
