I discovered that the feature enabling emails on replies to posts I had contributed to was disabled, if that happens to you, here is a graphic of how to enable it:
And in text:
1) Click 'User Control Panel' in the upper left of the screen
2) Click the 'Board preferences' tab
3) Click 'Edit posting defaults'
4) Change 'Notify me upon replies by default:' to 'yes'
5) Click 'Submit'
