separate accounts for family members

Yes you can.

Yes, but you are not going to be able to claim the bonus referral
You can create 2 separate accounts and then add yourself as administrator
That way you control all accounts and you get $100

Absolutely! I am about to do the same!

Better to have separate than single because of the $25 referral bonus as mentioned

Did you get separated accounts?

How do I call Fizz to join account? I am still confuised as to the process.
