Still nothing.  This appears to be beyond "disrupted" in scope.  In the past 24 hours I've received over 40 comments on my latest image and received zero comment notifications.  E-bots aren't slow, like when a broadcast newsletter is going out, they're nonexistent.  I have e-bots sent to an address that's pretty much reserved just for RR, so I tested it to see if it was my e-mail account that was the trouble, but the test went through immediately.  Apparently there's a problem from Renderosity's end.
