I'm noticing that I am not getting email updates anymore for people whose hubs I am following and have commented on or even if I get a new follower... They're not in spam, either. Someone replied to a comment I made on their Hub and by chance I came by that very Hub again and saw that the person had replied 5 hours previously... and I got NOTHING to alert me to this. Same with a new follower... what could be going on?? Thanks!
