Way to delete notifications?

Without reading them? Because my forum kinda had a glitch when I mass deleted someone's visitor messages, including one on my profile... and it's marked every single visitor message I've ever received as 'unread'.

 

I suppose you could always go read them again...

Can you not "Mark as Read?"

 

I don't think there's a mark as read option for visitor messages. And reread over 300 pages of messages?
