So, I went to sign in to my account yesterday to find that it had, in its entirety, been deleted. An account I've had here for years. My account, my posting history, all gone. Funnily enough, it allowed me to remake my account under my old username, but my history here is effectively erased. I'd like to know why and what could possibly be done to remedy this. Thanks in advance for any assistance. -Rob
