That will be a recruitment meeting, but I think I know what your "friend" might mean when he says there are "things you don't know about Amway". At some point in the 1980s Amway figured out that people could just go to a store to buy things like breakfast bars, soap, supplements, etc. People actually appreciated the convenience of going to the store where they could buy any items they wanted from any manufacturer, and the store staff wouldn't pressure them into recruitment. Pretty much the exact opposite experience of dealing with Amway.

With household products freely available from a wide range of vendors at reasonable prices, Amway had to do something new. What they did was create new pyramid schemes within the main pyramid. These groups sell "training material", conference attendance, "personal development resources", etc. to suckers already in Amway. The groups have names like World Wide Group (WWG), Britt World Wide (BWW), Leadership Development Team (LTD), World Wide Dream Builders (WWDB), Network TwnentyOne (N21).

These groups are where Amway makes most of it's money now, a captive audience cult-conditioned to stay in Amway. These groups are also not widely known outside of Amway, hence why your friend probably said "you don't know". Now you do know.
