I don't think the rally is a good opportunity to sign people up to be honest.
I'm not sure that people choosing to attend the rally will be the people most likely to have thought through what they want for the future of the club enough to be ready to fill in forms, pay $25 for three years in a row and wait the time to become voting members.
I agree that the club - not the people on this forum - should be doing more to promote the various types of memberships (FC, LC, STH, B&GA, RegE etc) that are available to fans and supporters. But I'm not sure the rally is attracting anyone that has thought things through more than an "oust Fitzy and everything will be automatically fine" mentality?
