Slack (https://join.slack.com/t/anoncoin/shared_invite/enQtMjcxMzUxMjk5ODYwLTU0OTJhNmIxNzYyY2JiMzUxOGZhMjYzNmQ3YmViNWM1OWIxZGNlMGY0Zjg1NzdhMDAyZmRiYTFhNTM1OWZiYTU) or IRC2P at #anoncoin-dev is the place to get in touch with the devs and get updates.

When it comes to NovaExchange I just got a reply from them saying that "The ANC tickets are at the beginning of the queue, and as soon our main developer is back on track regarding the open tickets, he will resolve all issues with those withdrawals."
