I tend to think of a supporting membership in that it shows a fens support fot the con, but for whatever reason can not make it to the con. I also think that trying to raise supporting membership now a days might be a bad idea.

In the old days IMO, I think people would get a supporting membership, and then as they could save money, get an attending membership.

Now, as it seems more and more Worldcons are adopting the payment plan method for attending memberships, increasing supporting memberships in the every increasing era of PDF publications should be looked at closer by concoms.

I just think that the Jan 1st increase was an oversight by Denver, and not really meant to discourage potential voters.

I can not see a voting only membership ever, and would vote against such a thing.
