There were a few moments of panic when I signed on and saw the message that "this blog has been removed..." but after having a code sent to our phone and entering it in and changing my password, things are up and running again.
Disaster (in my world at least!) averted!
edited to add: And now looking at my gmail I see what the problem was. Somehow while I was sleeping last night my email was apparently trying to spam my entire mailing list with some "pill advertisement" that google blocked (thank goodness!). Weird. I'll have to see if apple has any security updates. I'm hoping this is a gmail problem and not a computer-virus type of problem (usually not with apples in my experience...).
