First, I think the issue of awareness has to be a continuous agenda within Parliament to make sure that every so often the members are aware and trained about the new issues and problems that come up. It's not one-time training and you're done with it.
Second, I would disagree to some extent that it really doesn't matter when it comes to general election online voting or parliamentary online voting. The two main issues in online voting are verifiability and availability, or you don't end up having a case where people cannot vote, or you want to verify their vote. It was mentioned also that maybe a phone call afterwards should be used to verify. The size is not important here; it's more that you want to make sure that a vote is done properly and is verifiable in the end.
Again, I want to emphasize your point. I'm a big proponent of the awareness issue of programs within different departments in the government, and Parliament would be no different.
