Getting set up:

required: megatools, php, and bash

$ cd megareg-script/

$nano .account

.account:

EMAILDOMAIN="testing.com"
PASSWORD="p@ssw0rd!"

$ nano megarc/storageTest

Add the email domain and password as inputted in .account

Set up a mail server on your server for full automation. I use postfix virtual aliases for unlimited email addresses. This process does require a FQDN. I recommend buying your own domain name as it's fairly cheap (I pay $12 a year for mine, you can find it cheaper) or use the free duckdns or a similar service.

Use registerloop.sh to loop through a ton of accounts like this:

$ ./registerloop.sh 1 100

That will create 100 accounts.
