Hi How do you get access to the Data Integration community https://integration.anaplan.com/login/ as the site does not allow you to register or login with your existing login details. When trying to register it states "We do not accept registrations from that domain." Cheers Alan
You should ask Anaplan support to allow to register you at the site.
My customer has faced the same problem and Anaplan support has fixed this problem to this customer.
Have you been able to get to https://integration.anaplan.com/registration/? Not sure if the issue is within the registration or just actually getting to the registration form, this form worked for me. Good luck!
