Reminder on comments

If your comment *never* appears, that's not me, that's the spam filter. I have no idea how it chooses what to eat, but I have no hand in it. We get hundreds of spams a day, so it's an unfortunately necessary evil. I try to scan for caught real comments, but if I'm travelling, I may not get to it. If your comment has been lost in this way, just email me and I'll fish it out.

If I moderate your comment, I will, without exception, leave a note in its place explaining why. This is how I avoid the temptation to "disappear" good questions, as unfortunately happens on some blogs. If you didn't get a note, and your comments has not appeared, it's because I never saw it.
