I have just had 4 reminder icons appear, I duly clicked on them and
the message received was that a reminder had been sent to my
opponent, why when I return to the "your games list" are two of the
reminder icons still showing ?
I also have experienced the same problem from time to time, and I
suspect what is happening is your opponent has registered on this site
with an invalid e-mail address. When the reminder is sent, it fails to
reach a valid address so is bounced, and the icon reappears. Maybe
Chrismo or Ruzz can check this theory, or otherwise explain it.
