Disable snail mail communications from the start - email only?

[wozzza]

I'm so sick of getting stupid confirmations of changes ive made online, TFN/etc forms, notifications, welcome letters.. is there any way in commsec (or other way) so that you are defaultly registered for email correspondance?

Sure there are some things they have to send... but would like to avoid as much as possible.

Thanks!
