I don't really agree with that 1.1 post on the web, I can see it right there.. I don't need an email copy too (unless I'm a packrat, etc, so that's your 3.1 point from above)
As for 1.0, 2.0 and 3.0 above, those are user options right now.. just add the relevant Categories to your Watched list.
And 2.1 above seems to conflict with 1.1, and I'd vote for 2.1.
tl/dr - if we post on the web, we don't need a copy of our own post. If we post via email, getting a copy of our own post allows us to know it happened, and we can see any typos/errors/wrong-on-the-internet we've committed.
