Indeed, these are called discussion forums. However, not all topics are up for discussion!

You are of course more than welcome to send us an email if you have feedback about the forums:

Community feedback: do you have feedback about the forums, blog articles, live event presence, contests or community staff? We always appreciate such, and encourage you to send it to CMfeedback-EN@blizzard.com. Please note that while feedback mails are all read and taken into account we can’t respond to these.
