I do like the rules though I do agree it's not really necessary for only ourselves to be able to deliver the message - it doesn't change anything in my opinion. 
BTW I have no phone contact with anyone so if anything happened to me you wouldn't find out unless I found a way to tell you. Which brings me to the second point. 

Cel's point about death and such. I think in an extreme event of being hit by a car or having a death in the family or something like that, we'd all understand that sometimes it's impossible to warn others that something's happened or you wouldn't even feel like doing so. God forbid something like that happened, I don't think it would be an unforgivable sin to fail to alert us and only do so afterwards. We are all real life people and shit happens to all of us, however my personal opinion is that it's not impossible to say "can't post" in a 2 week period. 

Still, even if it is, the way I see it, this is the point of the 2 week grace period you'd be given to react. If we don't, the story would just move on, note, not resulting in us being expelled. You'd get two warnings before you are, and if I understand that correctly, that's a month and a half grace to drop in a 1-line message. I think that's much more reasonable than waiting for a month and a half on every single person to post. And again, in my opinion, it would be incredibly disrespectful to keep everyone in the dark and just disappear for a month and a half anyway.
