I can confirm, about 3500 OZC made it ok (with some maintenance and delay)
Since then several thousand OZC not delivered to address, emails received say it was sent.
Thanks!
UPDATE:
It appears all OZC have shown up to the address!

Thank you CryptoGiveaways.org!
Awesome! Yep all looks good! Looked through the block explorer, the blockchain seems to slow intermittently so would warrant a further look.
Thanks for the update! Much Appreciated!
