This includes both groups that meet in real life (IRL) (such as MichLUG and GardenSLUG) and online communities (such as LUGNET and JLUG). A group which focuses on building trains and associated landscapes is called an LTC (for LEGO Train Club).
A LUG may be open or closed, charge membership or be free an may allow only adults as members. It is advisable to check out a groups website and familiarize yourself with their new member policies before attending a meeting.
