I generally restrict my efforts to eliminating dubious sources and links from the articles I follow, and repairing vandalism, but now and again I do tinker with the texts of articles.
I use my real name on Wikipedia, since I'm willing to stand publicly behind my edits, although I do have doubts about the wisdom of that at times.
