I have users who haven't validated themselves. This could be
because they missed the email, wrong address, filed into junk
mail, or in my case due to server problems the email was never
sent.
How about adding an option in the "users administration" portion to
send a reminder message about the new account they signed up
for? It would be very helpful.
Taking it further, there could be automation. Send weekly/monthly
reminders x number of times. Then notify admin or delete the
user.
I request the "send reminder" button. The automation idea is just
thinking out loud! :-)
