I'll usually be participating in AfDs, fighting vandalism, and tidying up pages, along with grammar corrections. I typically won't be the person adding to an article, but I've done it in the past.
Wikipedia isn't the best place to contact me. Your best shot will be contacting my Discord account: incompa. Another good choice will be my email: [email protected].
I've also got an account over at the Simple English Wikipedia.
