I want to know:
- Was this domain re-registered after it expired? "I have no idea if domains expire and are re-purchased, and then the age starts from a later date.
- What was the other forum that Satoshi created (if there was any), and for how long it lasted?
If the forum was switched, the database from the previous forum was transferred, or a new database was created (you can avoid answering this one if some sensitive information were to be revealed).
Discussions were originally hosted on a sourcefourge mailing list I believe, and then the forum itself started at bitcoin.org/smf, then forum.bitcoin.org, and then was eventually moved to its own domain bitcointalk.org. I'm not sure if any migration itself was being done to any new servers but the DB theoretically should have been the same within SMF, moving between each address change, the forum would have just gotten a new address and ultimately the eventual name of Bitcointalk. This is why you see posts & users from before the domain was registered.
