It took me about 4 minutes to receive the email - once I got it, the servers were quite responsive.
Just give it a few minutes ... it'll get to you eventually
The servers are responsive because all the rest of us are locked out, still waiting on our reset email :-/
It's been 20 minutes since I submitted the reset, and I still don't have the email.
Edit: got email after 40 min.
Our email systems are somewhat loaded from the email announcement so it might be a little slow. Things are slowly improving in speed however.
