Hi, I was looking for an extension that allows me to create a custom block of only valid domains allowed for registration, but it doesn't seem to exist. The two extensions I tried (the first from the flarum team) didn't allow this, and the second isn't compatible with version 2.0. The list of available domains should be this one. I tried inserting it into extend.php, but to no avail.
'gmail.com',
'outlook.com',
'hotmail.com',
'icloud.com',
'yahoo.com',
'libero.it',
'virgilio.it',
'tiscali.it',
'aruba.it'
