I discovered Wikipedia over a year ago and since then have been trying to help out with various articles that I know something about. Some are to do with people I know personally or who are related to me. Some are to do with countries I have lived in as I grew up all over the world. I also have a degree in English literature, have had many jobs editing books, magazines and websites, and possess a graduate teaching degree; so sometimes I can help out in areas related to that. I also help from time to time with some simple copy editing of subjects that I know less about, just as I get a few minutes here and there.
I have especially been editing articles related to my area of most interest and knowledge, which is Mahayana Buddhism. I am a Buddhist in the New Kadampa Tradition and a student of Geshe Kelsang Gyatso. I have been studying (and trying to practice!) Mahayana Buddhism consistently and thoroughly for almost 30 years and have also taught it widely.
My tradition of Buddhism, Kadampa Buddhism, preaches religious tolerance for other spiritual traditions and the freedom for everyone to practice the religion of their choosing. I am prepared to debate with anyone who wants to take that freedom away, so you will regularly find me on the Dorje Shugden articles (as I rely on Dorje Shugden, who I regard as a manifestation of the Buddha of Wisdom, Manjushri -- and the Dalai Lama has banned the practice.)
I will also contribute to Wiki articles about animals as I believe strongly in their right to be happy and free. (But generally, I steer away from too many politics.)
