I really hate the buggy comment registration system here, and I know you do, too. However, it’s also been a huge help to me — the thousands of spam comments that were flooding in every day were throttled way back.
So I’m going to try something. The registration requirement is off, temporarily, just to let those people held back by the bugs get a word in for a while. It’s going back on on Monday, though (or sooner if the spam load becomes intolerable), simply because it eats up too much of my time if it’s not. So get your words in now.
