Your post goes into a queue and goes online in a few hours. We've been averaging about 12,000 pageviews a week, so some folks just as cranky as you will read of your troubles and offer a topper or commiseration in the occasionally lively comments.
If you just want to offer up some comments, that's even easier. You don't need to sign in or anything. Under the comment link you can choose "Name/URL" where ALL you have to do is type in your pseudonym. (No URL is necessary, though some wiseacres include a funny URL and bored users sometimes stumble across surprising links to erection cream, election results, or login pages for The Chronicle, our longtime nemesis. Longtime users, some with this page and a previous one for as many as ten years, find having a Google account under their user name handier, but it's not mandatory.)
Welcome to you. If you are a poor college instructor who has been vexed by students, colleagues, administrators, or parents...man, we are your people.
