Hi, if they say they haven’t enough money yet they must know what the costs are, and you’d assume it was budgeted at least indicatively on the day you voted acceptance of this motion.
Not a lot of folks can afford big hits to the hip pocket and aren’t usually advised to borrow it, so accumulating funds is not unusual.
If you want to revisit it get your own thinking done, then hold a low key meeting to discuss it – probably initially without the committee so you can really feel what folks want, then take it to the committee as a group that’s prepared to EGM it if you have the numbers and don’t want to wait further.
