In the demos I've done, it takes sometimes an hour for zoom to process and make available a 90 minute demo recording. I can imagine that a 7 hour recording might take a bit longer. Then someone has to probably split it up into sections so it's easier to watch, which will also take some time. I expect the folks that will do that are pretty busy supporting the live sessions, too. So give it a few days and if you registered, you should get an email with link(s) to the recordings.
The auctions appear to be a separate thing - I did have to register for an account at
https://auction2020.woodturner.org to view the live auction. And it looks like there's a separate registration if you want to be approved to bid. It was "live" in that they opened bidding for one item, and collected bids via the site. There was an auctioneer in a little video window calling for bids.
I don't think you need to register just to look at the pieces for any of the auctions. The closed auction from last night can be found under the "Finished Auctions" link there, if you want to check out the results.
