Your profile is already capable of letting you know when someone has replied to your post. You need to set your subscriptions to posts to get that. You can have the forums do it automatically:

Messaging and Notifications: http://forums.psychcentral.com/profi...do=editoptions

or you can do it to any thread on the thread itself by choosing from the blue menu, "Thread tools."

As for hugs, no, unfortunately we can't let you know when someone has hugged you on a thread at this time. It's a good idea, so we'll consider adding it in the future.

Best,
