Multiple simultaneous logins, paid users only, one free login per each paid login

Previous feature requests have asked for multiple simultaneous logins.

Here is a suggestion that will make it profitable to allow multiple simultaneous logins.

Allow multiple simultaneous logins for all paid accounts, and allow as many free logins as there are paid logins.

Person A could buy two paid accounts, and be able to have the two paid plus two free accounts all logged in at the same time.

Person B might have a single paid account, and be able to have that plus one free account logged in simultaneously.

Person C, with a free account, doesn’t get multiple simultaneous logins.

This way we minimize misuse while giving people a good reason to upgrade to a paid account.

In one typical case, a user might have a paid account for work, and be also logged into a free account for personal use.
