Today I flagged a question as needing to be made community wiki. I thought about why, and found this old question of mine here. Carlo Beenakker helpfully linked to a thread on the old tea. Link reproduced here. But that tqft place is down, as well as the tea place that redirects to it, as Martin pointed out here. I could not find a copy of the relevant discussion Carlo linked to anywhere online, including the Wayback machine.
Can someone find these old threads and make them available again?
