      The CTL\SUBRATE.DBF database stores an unlimitted number of
      subscription rates.  Each entry includes the minimum amount,
      a description, and the number of days before expiration, as well as
      the TBBS user template for upgrading and template for downgrading
      users who subscribe at this rate.  When a user enters a subscription,
      the HIGHEST rate that either matches or is less that his contribution
      will be effective---the user will be upgraded according to ONE rate
      only and will not be upgraded based on any lower subscription rates
      that may have been defined.

      To DISABLE rates, delete the CTL\SUBRATE.DBF file.  If rates are BOT
      enabled, the system will accept donations without upgrades or
      expirations.  If rates are enabled, a TBBS user template will be used
      to upgrade users, subscriptions will expire after so many days, and
      another template will be used to downgrade the user.  From within the
      rate editor, the following commands are available:

      Use cursor keys/Home/End to move between records.

      <E>dit:   Change the current subscription record.  ONLY subscriptions
                validated AFTER the change will be affected.  If you wish
                to edit previous subscriptions, they must be changed
                manually from within the viewer.

      <A>dd:    Append a new subscription rate to the end.  The operation
		of The User Subscription System does not depend on what
                order the rates are listed.  But the rates will be
                displayed to the user in the order that they appear in this
                file.

      <I>nsert: Insert a rate at this point.

      <D>elete: Remove rate from the file.

      <H>elp:   Read this file.

      <Q>uit:   Exit and save changes.
