Well, a couple thoughts on Rich's situation. (Rich, substitute your/you whereever it fits.

)
This is not said in any kind of negative tone whatsoever -- I would be surprised if Rich ever joined a project like this ever for reasons he has stated...the sheer amount of effort involved on his part.
And true, this talk comes up at least once a year...
Anyway, things to hash over:
Possibility 1 - Make a general rule that any snake coming from Serpenco is registerable by the new owner as a "XXX" phenotype (whatever is known). List parents as "Serpenco Stock" and let the lineage continue in the register from there. It won't completely eliminate the holes that will be left, but at least give an explanation for why the hole is there.
Possibility 2 - Make it so that a breeder can register a clutch and that clutch is given an ID number. No pedigrees to keep track of, no paper to keep on file...just a clutch ID number. The Clutch ID Number goes with the hatchling and the new owner can register the snake with the registry. The registry will then fill in the parent's ID numbers (assuming the breeder registered the breeders) or fill in, again, "Serpenco Stock". Phenotypes can be submitted if known or listed as "Unknown" or "Unlisted". As to getting a clutch ID number...just submit number of eggs, ID of parents (CSR number or Serpenco Number or whatever), and a number of each phenotype (helpful, but optional). A set of numbers is assigned for that clutch and if the new owners choose to register, they'll get their ID number and the records go on.
Possibility 3 - Make the registration info of genotype and parent's genotypes optional...breeder can list genotype as Unknown/Unlisted if they so choose to protect the Colonel's Secret Recipe. Same with phenotypes. On the list, it can be listed as "Anery type unknown" "Hypo type unknown". For those animals that we don't know what they are...or don't want to say...they are "unknown". This isn't any worse than just having "Serpenco Stock" listed on the pedigree. I don't see a problem with it.
What I do like about a registry is it gives each individual a permanent ID number. With that number, you can trace back through the lines (eventually) as far back as we have records...but the benefit is if we can get enough people involved, you can trace back through multiple breeders.
As to getting it started, if we can just get people to submit info on their breeders for now with whatever info they have or are willing to give, we can get the train started. We won't have a lot of info on them at first, but soon the pedigrees will grow.
On the subject of pictures. I would say for this first big effort, make ID pics requested, but optional...get the breeders input into the system with at the minimum an ID number and hopefully a phenotype. Then later, start with individual registrations from then out needing one clear dorsal shot (perhaps a belly shot for bloodreds/motleys/stripes). The big breeders should not have to do this except for possibly new snakes entering their collection here and there. The burden would be on the buyer to submit the papers to make their pet registered, the breeder need only register the clutch with a little info and get a clutch ID number to pass on.
