No more comments without logging in to Livejournal

Sorry, but I've had about enough of "comments" to posts here (some of them very old posts) that exist purely so as to contain links to some places that are, to put it gently, irrelevant to the subject of the post. Setting this won't stop all of them, since some spammers do register, but it'll stop most: I may change things to limit posts from anyone not on my friends list if it gets bad.
Anyone who tends to comment on the Facebook mirror of my public posts here rather than directly won't be affected anyway.

Damn it, pneumonia, go away! Look, I shake pill-bottle at you!

That's two nights in a row I've had trouble getting to sleep because of coughing, two mornings in a row I've woken up before 5 due to coughing, and two days in a row I've been tired, had problems concentrating, and gone mildly feverish by early evening. I'm taking the penicillin. I'm resting, I'm eating sensibly, Vit C intake is way up, I'm drinking plenty (and I don't mean alcohol). I just looked back through LJ, and I see posts about coughing, colds, and not going out because of being too ill dating back to November. I'm BORED with this!
