Is there a way to easily follow comment conversations in a HUB? Do you get reply notifications?

You can go to "my account> comments you made " link to keep track of where you commented and if there is an update to that hub for comments for last few hours or days. Other than that I didn't see any feature inside hubpages for keeping track of conversation. If you own the hub then you'll get confirmation when you get any comments.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
