The Sent Messages box in the Private Messages menu shows me a count of 0, even immediately after responding to a PM. I only checked for the first time a few days ago, after the site seemed to have had a crash, and thought maybe earlier messages had been lost or something. But it's still the case today.

Not a major emergency, and maybe I'm the only one, just bringing it to your attention.

Thanks for dealing with all the evils of the internet for us!
