Downloading Posts

I have tried twice now to download my posts and it has not worked either time. It says I will be notified via private message but it never comes. Is this a working feature or not? If it isnt, there should be some sort of notification that its not.

Of course it worked while I was not online for 8 days (and its only good for 2)...well, at least I know it works for all the good it did...guess I will try again.
