Is there a way for me to get auto email notifications for new responses or comments to my questions/answers/comments? Surely there is a better way than constantly refreshing every so often? :-)
If I read your question correctly, you'd like to receive email notifications for new comments or responses to your questions. look at the following screenshot:
This is the screen that appears when click on Ask Question menu on the main site. So, when you write the question, you may utilise this option to do exactly what you'd want to do: receive email notifications for responses or comments on your question, comments on your answer.
Do note that SE does not clog your inbox by sending you an email every time a new comment/answer is posted. An email is sent if your question has been commented on and no other notifications come till you visit the site (in response to the email). However, another notification will follow if your question received an answer. And the same goes for newer answers!
However I am not sure what you'd do, if you asked a question without exercising this option and later you make up your mind. I'll leave this to someone else.
Also, the email preference option Dylan has mentioned in his comments are about receiving mails for questions that come to the site with your favorite tags and I am not sure if this will satisfy your needs.
