You will see various options in the right-most column depending on your current plan:

• • Change Plan – Change to another plan:  Basic or Premium
  • Subscribe – Subscribe to this row’s plan (Name in column 1)
  • Cancel – If you are on a paid plan, this will cancel the plan (and is supposed to cancel with your payment provider [Contact me if this does not happen]). Afterwards you should be on the free Basic plan.
  • Update – If you are on a paid plan, this is to update the payment information (say change the credit card number.)
