   if that doesn’t work so I can look at it please.

 * After adding an attendee to the wait list:
    Order Details:
 * WAIT LIST

   confirmation.php on line 191
    Test Event:
 * You are on the waiting list.
    This appears to be a bug.

 * I have experienced a problem sending attendee confirmation emails. I’m using 
   WordPress 3.9.2 Event Registration 6.01.07. It appears that If I register 3 or
   4 times that I never get all the confirmation emails. I’m not sure what might
   be causing this problem. Its not a show-stopper but more an annoyance. I also
   had to add a plugin WP-SMTP-MAIL-CONFIG to get the confirmation emails to work.
   I would like to some day donate but I keep encountering numerous little problems.
