Hi, I'm a peever from Ann Arbor Michigan who dislikes mechanical errors and poor writing, so I like to go in and fix this and that, hopefully without seeming smug about it. I am not likely to change an article in a way that challenges any contributor's knowledge of the subject, unless he/she has injected a personal opinion into the topic.
I am a professional musician and teacher and have considerable expertise on topics involving the jazz vibraphone.
