If you enter your email in your profile, you can get alerts by email when someone comments on your post, replies to your comment, or starts following your hub.
In your profile, you can select which of these alerts you would like to get by toggling the 'comment-alerts', 'reply-alerts' and 'follower-alerts' fields.
Please let me know ASAP if you have any problems with the email alerts. If you are not getting email alerts that you think you should, check in your spam/trash folder.
As always, feedback on email alerts, or anything else is appreciated.
