If you join Enotes.com for free you get only one free token that can be used to access a page with premium content. You have 48 hours to use it after you join, else it expires. You do not get any more free tokens on a daily basis.
For accessing more premium content once the free token has been used or has expired after the 2-day deadline, you will have to buy a paid plan. These are very reasonably priced and could cost as little as $4.16 per month if you buy a plan for a year. You will also be able to ask 3-5 questions daily, and receive responses for the questions you ask with a priority response time.
Have a look at the other benefits of the paid plans at the link provided below.
