I just installed post2mail, which should send me an email with a link to this post. if it works, I’ll do these 2 things:
1) make it easier to update the list of recipients (I sort of like the way it’s done in Update Notify)
2) make it only send from a single category
3) ideally, send the actual post contents, instead of a link (or in addition to, I suppose)
okay, so it does send the actual contents; amend that to sending HTML mail. I think.
wow, I’m dumb. it’s just a configuration option.
only it doesn’t convert the line breaks. why not? and what about 
images?
just tweaking.
