I think the difference implied between being "FedEx certified" as compared to "Reptster certified" is that if somebody took the time and effort to jump through the FedEx hoops, they are PROBABLY more experienced and committed to the shipping process than somebody who just watched a video. Of course, that is not an absolute guarantee, just a likelihood. Basic shipping is pretty simple, just like learning the basics of driving a car. But just like driving a car, being REALLY good at packing and shipping takes a lot of experience dealing with adverse conditions. With experience and a lot of thought, one learns how to best deal with shipping in extreme temps, and also how to best deal with the idiosyncrasies of a particular shipping company. The new Reptster shippers will eventually become GOOD shippers, if they do it often enough, and pay attention to solving any problems they, or others, find along the way.
I think it would actually be a good idea for Reptster to offer their shippers a "REPSTER CERTIFIED SHIPPER" (maybe with a date they shipped their first Repster package) seal or something similar, to put on their websites. That would benefit the user, promote Reptster's shipping service, and avoid any confusion between those who are FedEx certified, and those who are Reptster certified.
If David or any Reptster employees are reading this thread, I would like them to comment on this idea, and also the idea about posting a FedEx "permission / authorization letter" (maybe even update the date on it every year or so) for users to print out and take with them when using the Reptster account.
