Afternoon trading November 28, page-184

Folks. Hope some can assist.
Understanding some may be doing many trades across many companies, 10mins to x days.
How does one deal with all this paperwork. Have mercy on my po box.

Im noticing investorserve, automic,linkmarket services, computershare etc,etc,etc.
Does one have to register with all to cover the electronic communications.

Logically the answer feels a yes.
However I am just wondering if there may be a less intensive way to update details and receive correspondence.

Cheers,
