I recall when I asked my first question that there was a checkbox (that I checked) instructing StackExchange to send me an email when an answer (comment as well?) was posted.
Answers were posted but I received no emails. Did I do something wrong?
When I posted subsequent questions I could not find that email option.
Am I missing something?
You should see this on the Ask Question page:
If you click (settings) it will show you frequency options, for a maximum frequency of every 3 hours.
It's possible that the email wasn't sent because you had viewed the post in the intervening time — I'm not sure if it works similar to the inbox (which I believe by default will email your notifications for answers, comments, etc. only when you haven't viewed them in about 48 hours).
