I was looking for the article saying that we should add a space before or after breaks, but couldn’t find it anymore, I’ve read these articles and discovered new things:

I think the article about “How do I delete my subtitles?” needs some modification: subbers can delete subs from the subtitle editor (and avoid entering the segment timer).
