Do I need to post my order here?
Certainly not, but it does help us keep a tally of when orders were placed, how many there are, total hash rate, etc. The more data the better, even though the vast majority of orders aren't posted.
I also didn't receive an e-mail confirming my order, ever when I did pay with bitcoins in less than 5 min after placing it.
I've seen it take an hour for an email to come through, and I'm sure they're probably awaiting a network confirmation on the Bitcoin payment before acknowledging the order. I'd give it a bit and see what happens.
