Earlier today I was trying to log in and had forgotten my password. I filled out the "reset password" form and waited, but the email never arrived. I tried it at least five different times. I was definitely using the right email address, because when I tried a different one it said it wasn't registered.
I checked my spam folder. I added
community@mobileread.com to my contacts list (which should have whitelisted it on Yahoo mail). I made sure Adblock was turned off on mobileread before submitting the form. No email ever arrived.
Finally I was able to log in by remembering what my password was. So, now I don't actually need my password reset. But this issue might be happening to other people.
