Hey all! I'm Mdann52, or feel free to call me Matt. I've been editing Wikipedia since early 2012.
As for what I do, I'm a ArbCom clerk, I respond to OTRS tickets, I'm a member of the Account creation team, and I occasionally do a few other behind-the-scenes maintenance jobs. I don't really write and expand articles as a general rule - if people ask me to, I will happily indulge in some writing, but the fact is most topics I'm interested in are covered well already, so there isn't always much I can add to them.
I'm (usually!) glad to help with any issues you have - either technical, general, course-related or just for a chat - my talk page is that-away for any enquiries :)
