I am also unable to get through on any of the MyAlli site links. Says "Page Not Found." There is this message on one of the pages, but only good Monday through Friday.
"If you’re having technical difficulties with the web site or with your enrollment in myalliplan, please call 1-877-4myalli (469-2554) M-F, 10:00 a.m. – 6:00 p.m. ET (English/Spanish) for assistance."
If it has been going on for a couple of weeks, we may want to call on Monday. Maybe they aren't on these message boards too often.
For some reason, they also have an incorrect join date for me. My join date was April 29th.
