well if im signing a petition i dont mind putting my address – or just my postcode to give general area, I dont like leaving the whole address, am funny bout that sort of thing – and if it insists on phone number i dont sign it because quite frankly i dont want to give my number out – so yup, maybe ask for it but dont insist on it.
i was thinking of making the address and telephone optional but i wasnt sure if they would have to cheque the names so would require an address or number
