SMF1.1:Members

A member is a person that has Registered on a Forum. It is usually beneficial for a Guest to become a member if they intend to Post or use the Forum more than once.

Members have access to Profile and Notification Options that are unavailable to guests. Members can also be placed in Membergroups, made [Moderators]] or Administrators, given special Permissions, and access members-only areas. Being able to send Personal Messages, receive forum e-mails, and post new Polls and Topics are some additional benefits that may be available by becoming a member of a Forum.

By default, a Forum can support 16,777,215 registered members. However, this limit can be raised relatively easily.
