A LUG (or Lego User Group) is, according to the LEGO Ambassador Network documents:

A group of individuals who are passionate about the LEGO experience and have formed a group.

To become an RLUG (or Recognised Lego User Group) a LUG must meet certain criteria:

  • Been organised for a minimum of one year
  • Have a minimum of 20 members
  • Participate in or host three AFOL events (exhibition, display, or convention)

Becoming an RLUG affords certain benefits to the LUG and its members by The LEGO Group.

Find out more about LUGs on the LEGO Ambassador Network website.
