EDIT: If you get a funky email about your Curse account, it looks like it was simply a site hiccup. Here was what I got:

Your CurseID password has been reset. To login, simply enter your username or e-mail address and the following password:

We encourage you to change this password as soon as you login.

Notice that it didn't send me a temp password, just an empty space on the form.

Here's the scuttlebutt on curse from the mods:

Hi, this was an empty mail template for the password reset functionality accidentally sent out by our bulk mail provider. This is why it doesn't include the new password, which password reset emails normally have. You may safely ignore / delete this. Your passwords have not been reset, this was only a goofup on the part of our mail provider.

If there was a link to their page in the email I would be very suspicious and look carefully at where that link might take you. It sounds like a phishing attempt....

There were no links in the email. I think I found the culprit, see original post.
