Sorry for the inconvenience, but I have to withdraw this thread.
Dynadot just sent me retroactive order cancellations on all these domains. They showed available before registration, and they showed in the account after registration, and Sedo accepted them into my portfolio there...
but today Dynadot credited back my account and the domains are gone!
(P.S. --- Sedo's automated price recommendation tool came in at $330 for fat.so, $110 for 252.so and the ($100) Sedo minimum for the rest.)
So there's nothing totalk about any more. sniff...
