It would do the same thing, but in a different and more annoying way. It sends us e-mails. That means we probably won't get it because not everyone checks e-mails. If someone is online, though, and he visit WEForums, he will get the PM (usually). It works better through PM because it's more guaranteed.
I check my e-mail once or twice a week.
Oh, and you can also PM me if you 'need' something closed if it doesn't work.
