I think it is a good idea. However, the membership including a lot of the officers are not particularly au fait with computers and internet technology. Whilst I think your idea should be investigated, it might be seen as:
1 Taking the outcome of the vote for “proxy voting” for granted
2 A step too far too soon for those same people
I suspect it would have to be done on a closed section of the site only open to members. Otherwise how would we know who was voting.
I’m not trying to dismiss the idea but as I said previously I tend to look for problems in advance as it equips us better to answer those who disagree.
