Hi Chris, this forum is done by each thread. If you want to receive an email notification of replies, you will have to check the box under your reply. Otherwise, you can Subscribe to a section to get notification of a new thread. That is the current format as of right now. Thanks.
This forum is much different from what everyone is used to. When we have time, we will review the option of an auto-notify, but as of now, I do not believe that is an option.
Just remember, the notification option is there, you just have to do it for each thread you reply to.
