Preventing freshman flight?

[Amy33Amy33]

How do you guys prevent freshman from quitting right at the beginning of build season when meeting frequency increases, and how do you continue to benefit members who cannot meet every day of build season? Also how do you schedule build season to still build the robot and prevent member burnout? If you don't do this, how do you manage a culture of attendance where members come to meetings and multitask? Do you divide the days that different sub-teams meet to increase focus (loud sub-teams on Mondays, quiet sub-teams on Thursdays?) Do you have an attendance requirement for lettering, or an accomplishment requirement? What has and hasn't worked for robotics scheduling during build season? What secrets do you have for keeping on deadline?
