Occasionally I run across sites with a few examples of how to use Sub Station Alpha subtitles, but I haven't found a really good guide of how the tags work, most just tell me to use a subtitle editing program, and there aren't any good ones for mac.

I've tried going to the SSA homepage, www.eswat.demon.co.uk, or emailing the author, but neither reach their destination, and WhoIs says the domain doesn't exist. Did it move or was it shut down?
