Same here. This is a pain in the butt. I did one. I save the other 4 for later.
Glad it was opened to you, idk why but the whole thing can seem daunting, and it takes a village.
My bad if I hadn't somehow made that clear in the past. They are currently updating everything so the underpinnings may somehow get taken for granted.
Just an FYI, if it says the cert is under another registered user, which happens from time to time when the book either new to you or whatever that is normally fixed by a pick of the book and a pm.
Getting ahead of myself. But the past registry user has to ok the transfer if they already had it in there own registry, when you then have bought it and try to transfer.
When you try to register in the registry, it will send the past owner an email to "transfer it."
If that doesn't work pm @jstam with a picture in front of a time-stamp like a monitor or laptop with the registry open, then admin can manually see proof of ownership to manually transfer.
It may seem like a pain, but is good news when you own one and it is registered, as no one should be able then to use your cert otherwise YOU'D get the email and can deny the transfer and pm admin to make sure etc.
Registry imo also helps you keep track of books for cert numbers, cutting down on theft and reports or etc. kind of like a serial number.
Then if it gets tried to transfer go from there, and long story but is some of my theory of benefits to it. Seems more "official" than a unnotarized piece of paper idk 😶😐
