Here's one for all the family.
Because so many of us are getting so into this, people have been saying they're missing new comments and posts. I get them all delivered to me by default so I don't miss anything but there may be a way to extend this.
If enough people are interested we could sort a way so that anytime anyone posts or comments you get a mail with the said post/comment in it and thus you miss nothing. I realise this may seem slightly obsessive/completist but if enough people are interested I'll investigate setting such a service up for anyone who wants to opt in!
Let me know in comments.
