Password Reset Email Not Working
Assuming the account you're talking about is prismbox...
I can see the email went out and Greasy Fork didn't receive any immediate error. I also tested on my account using the same email service as you, and I got the message (though I had to tell Gmail that the email wasn't suspicious). Have you checked your spam folder?
I found the email after I resent it again. Sorry about that.
I get emails for notifications of discussions on my main greasy fork account (this current account is temporary), but when I ask for password reset instructions, I don't get the reset email. (my password manager deleted my passwords...)
