That's a good point about bid increments. If I had to explain eBay's small increment, I'd say it's because eBay is trying to mesmerize people into bidding a little bit more and driving the prices even higher. Kind of what we want to do too, although we don't want leave someone feeling guilty the morning after. Maybe we could do it too if we had automatic auction software that would handle a large number of bids without consuming pages of the forum. Until then, we know what the NASC bid increments are and will bid accordingly.
As for the NASC membership thing, that's the nature of every new organization. It looks like nothing is happening because of all the time required for organizing. And the few people motivated enough to do a lot end up doing everything.
