It seems quite clear that a monthly payment system is not cost effective.
Might FSFE implement a lower fee for the unemployed (of which there are far too many these days) and for students? I have met lots of out of work developers who start to fool with linux, perl, php, etc. and find their way to FOSS when they are unemployed or under employed. Fellowship with the FSFE, when affordable to those in temporary financial difficulty, could be something to put on a CV.
This symbiotic relationship between the FSFE and the greater software community could increase the FSFE's value as force for positive change.
Might'nt we implement a one year only membership for 10 euros? A student or developer good join, pay 10 euros for one year, and if the want to remain a fellow, then pay the normal 60 euro rate? Or perhaps we could have this program be a four year program to reflect the amount of time one spends as a student.
