I am currently 36 years old and a non-union stage manager in Chicago. Fun fact: I have a super-long degree (B.S of Theatre and Entertainment Technology with an Emphasis in Electrical Engineering Technology and a Concentration in Stage Management) from Michigan Technological University.
Generally I spend my time on Wikipedia patrolling the recent changes page, with logged-in users hidden. I will usually investigate any large character differences. I have a very basic grasp of wiki markup, so until I learn the intricacies of markup I will be limiting my self from page creation and major factual contributions to articles, as I feel like my edits would look like crap. so thus I limit contributions to things that I can actually do, namely fixing vandalism and the odd spelling error/grammar error that I notice.
If you see me undo an edit, then that generally means that there was vandalism and either the vandalized text was too complicated for me to retype, or there was too much text to fix by hand. I have very little sympathy for those who blank pages or replace pages with garbage, so if you do so, your reasons better be very well justified on the article's talk page.
