Hello mustang and thank you for your comments.
You are correct that the WTBTS could very well put up a fight against electronically submitted DNC demands. They could claim (incorrectly, in my opinion) that even a remote possibility of error or fraud would invalidate the entire effort. To slow things down further, they might also require the DNC demand paper be signed by the householder and sent to the Kingdom Halls instead of Brooklyn. This I think is the worst case.
Yet even then, they are still set up to get a flood of DNC demands. And here is how we can do it:
1) Volunteers organized via the Internet are assigned territory. For each Kingdom Hall in the territory, the responsible volunteer identifies the legal mailing address of the hall, the hall phone number, and perhaps some other contact information. This is sent back to the project web site for archival purposes.
2) Each volunteer produces a mailing list covering some residential segment of the territory. There are various sources for this, some public and some commercial. The web can be used here as well and there are sites that can crank this out, at least for those residences that have a listed telephone number. The segment mailing list is then sent to the project web site.
3) For each address in a segment, a letter is generated (by computer, of course) that includes: an envelope with the DNC address, a one page description of the DNC project (this includes the KH contact data), and a pre-paid, pre-addressed postcard. The postcard contains the DNC address in its body along with a standard DNC demand and a space for the householder signature. It is addressed to the local Kingdom Hall. All the householder has to do is sign it and drop it in the mailbox.
4) The project web site will keep track of which territory has been processed to avoid duplication that would only be wasteful and could annoy the householders.
1) Yes, this is going to cost. In the USA, the cost per package will be about US$0.70 including postage and material. It may be more in other countries. It may be less if non-profit mailing status can be obtained. The cost could slow the effort, and it might become advisable to ask for contributions. But I'm rather set against asking for money. I did enough of that in the field service.
2) Yes, there is a greater dependence on volunteers. I'm not concerned with this as there are millions of ex-JWs out there and I'm sure at least one in a hundred would be willing to help. Also, more than a few of them feel regret leading others into the WTBTS and would see this as an opportunity for atonement.
3) Yes, there is less opportunity for accurately tracking the response rate. I suppose we will just have to look at the annual WTBTS statistics to see how the effort is doing. Perhaps the first indication of progress will be the condemnation articles that are sure to appear in the WT.
It is important that the one page description of the DNC effort be short, easily understandable, neutral (I would include WTBTS contact information just to be fair), accurate, and legal. I doubt if the typical householder is going to be interested in what appears to be propaganda or advertising for opposing viewpoints. A side effect is that there just might be a few who become WTBTS converts; a sort of collateral damage. But each person should be free to chose their own destiny. I just want them to be informed.
