I had an 8-month stint as Sentinel last year before willingly relinquishing my position due to work overload. Now that I'm free, I'm looking to return to staff because of an apparent shortage. Not asking for much, just Sentinel privileges so I can patrol recent changes once or twice daily (delete pages, move with suppressing redirect, etc.) I've also been on this wiki for about two and a half years now, give or take and have over 3,000 edits (that number would rise to 6,000 or more given my presence on the DcOW wiki for the first half of my time here.)
My old application is buried somewhere in this mess.
