Australian Ethical Investment sent me a Annual General Meeting notice with a paper proxy form and the option to vote on-line. The on-line service is through Boardroom Limited. This requires entering the share reference number and a voting code included on the proxy form. I then got a screen which was blank, apart from: "Time out (3 minutes) ". After ten minutes no more had appeared, so I pressed enter and got a "time out" screen.
On a second attempt I got "Validation Failure".
Having on-line voting is a good idea, but it has to actually work.
