YES – I’m pretty sure I understand what it means to be a join 
I believe the number is $100 …
Not really misleading to me – the conversion ratio is still way too low if I add registration AND joins … PLUS if you have for example 15 r+j every month for say 24months and the program says they concentrate on rentention – youd have 360 players x 30% (assuming they could retain just 30%) youd have 108 players playing in the current month.
Assuming you continue to average r+j you would expect that the # of players you have the next month to grow … for me it hasnt.
