Greetings! I am primarily an English Wikipedia user: Ipoellet. Please feel free to contact me there!
My main activity on Commons is taking and uploading photographs of places listed on the US National Register of Historic Places, especially those in Oregon. I putter at a lot of other stuff, however, especially categorization. I don't have or want a lot of special user rights, including admin, but I might stick my fingers into about anything that doesn't require special rights.
I contributed to Commons for several years as User:Werewombat, but finally switched to Ipoellet (my ID from English Wikipedia) when it became no longer avoidable to use global signon. So if for whatever reason you wish to see my complete history, check both usernames. Thanks!
