There was a thread about paying for more content to try to raise the amount of money PFS generated for Paizo in order to possibly increase staff to handle increasing scenario output.
I had recommended having some sort of opt-in program similar to what RPGA did where players could have some sort of paid PFS membership that would provide some sort of non-mechanical benefit. Having some sort of way to vet actual book purchases would be worth the $ to me to be able to use photocopies rather than having to haul around crazy amounts of physical product. From what I understand this might actually help Paizo since physical, rather than .pdf, product is a main part of their financial strategy (see the many many posts by Vic about why there is no .pdf subscription plan) and continue to support PFS as their main tool for marketing at the same time.
I'm not sure what specific form it would take, but might be an alternative to "have VO's sign off" (especially as there are hundreds of VO's out there and it's doubtful a VO from CA would recognize the signature of a VO from GA).
I would pay for this.
