Good to hear all is back to normal!
I guess with all the emphasis on web security these days, web host services, etc. are HYPER-sensitive to any "suspicious" activity, but I never heard of them actually taking down a site because the owner/administrator emails to the membership. Hmmm! Well, I guess the moral of this story is ... next time you have to make a mass email, you need to set up a membership email list in some other email system like Yahoo, and do the email from there
or is it
They even bounced back an email I sent to you (replying directly to your mass email) saying something like "unknown user" as the reason!! They knew you when you sent in out, but they didn't know you a day later
Ahh the benefits of modern technology
But, one serious suggestion: in case of this happening again, you may want to make an FB (FaceBook) page or even "group" as an alternative site where (at the least) you can post a "status message" to us all ... there are actually quite a lot of watch related FB groups & pages now.
