I've been around for a while, but mostly just fixing up little bits and pieces as I run into them. When I'm bored and have nothing better to do, you'll often find me roving around Wikipedia, reading random pages (or pages from lists like the copyedit list) and generally improving little things like grammar, phrasing, references and the like, wherever I can.
I also like making charts and graphs, so I jump in and do that now and again as well.
I will leave you with what may quite possibly be the cutest picture on all of Wikipedia, which I discovered today, this 22nd day of October 2016, when confirming that I was right about why calico cats are calico. May it improve your day as much as it improved mine.
