Good point. *Much* more work, as the amount of share trading would multiply up, probably much more than 10x

I think  a stock split would only "work" therefore if a dedicated trading platform was launched, so all the laborious manual work was removed once and for all.

The current direct transfer system done via email honestly isn't much good though. The manual labour for friedcat + cases of attempts at "double selling" (not sure if any successful?) which friedcat confirmed recently. Its not the most secure way to trade shares is it ....
