I’m not sure where your quote regarding forum about "notifications"? It sounds like it is to do with email notifications if you decide to follow a specific thread. Can you point us to where you found it?
But in general you are free to interact with the good folks in these forums as much or as little as you are comfortable with or indeed your time permits!

As for Heroes and their exploits, I’m a sucker for a good myth or legend, I grew up on Greek, Celtic and Norse myths!
But yes they are a bit one-sided when it comes to the “monsters”, we rarely get to hear their side of the argument!
It's not only History that is always written by the “winner”!
Recently read Stone Blind by Natalie Haynes which gives an interesting perspective on the story of Medusa from her perspective.
