How to create new accounts in SEO Content Machine
Each SEO Content Machine account (login) can only support login to one instance of the SEO Content Machine program.
If you want to add another subscription for a different server you should create another SEO Content Machine account with a unique login.
Logins in SEO Content Machine are based on emails.
If you already have an existing account, you can re-use the email via a plus address.
Eg:
Main account = john.smith@gmail.com
Sub accounts = john.smith+lic1@gmail.com
Just add a +lic1 +lic2 +lic3 etc
You can only log into one instance of the SCM APP per email address. Simultaneous logins are not supported. If you log into different computers using the same email, SCM will log you out of the others instances automatically and your tasks will show an error.
