But how does one handle password resets without resorting in one form or another to sending some info in plain text to users?

At least one website on the current front page is there because it sent a temporary password in plain text. I assume this happened because the user forgot his password. This says nothing about how they store passwords and after all how else would you handle a password reset? Send a password reset link? That's the same thing.

Sending passwords in plaintext back to the user after he has set/changed his password is clearly a security risk but when it comes to temporary passwords or password resets how else would that info be sent?
