We have recently made two improvements to the Notifications system that we hope will improve your experience on HubPages:
1. There is now a "follow" button on all Forum topics. If you follow a Forum topic, then we will email you when posts occur that we think will be of interest to you.
2. We have changed the behavior of the "follow" button. Previously if you followed a Hub or Question we would email you about all comments or answers that occur after you follow it. We are now attempting to email you only about comments, answers and posts that we think will be of interest to you.
