From here: Message Wall is a communication tool that allows you to send public messages to other users.

It's a so called Wiki Feature, I'm not sure what else you want me to explain about it though? And as for why they count as edits, I suppose that is just how the platform was set up once upon a time. But you could always try asking an admin, they might be able to tell you more about that.
