The post said AHA is moving on Friday. It's only Wednesday here - time zone?
ahamemberdeals.org is working fine for me in IE11. I've had trouble with it in the past though. Different browser seamed to help.
If you're an AHA member, I think they're listed in Zymurgy. Or I might be making that up.
Edit: Foolish me - You wouldn't be asking if you weren't a member.
