Where can I find the very first thread posted on PF? Is the author still around?
You can try here:
We've come a very long way and I'm proud to have been allowed to have been a part of it.
If memory serves me well webarchive doesn't store individual threads, just a main page of any forum (well, it is more complicated than that, but I don't expect it to have more than just a bunch of main pages stored).
From what I was able to quickly check this is the oldest surviving thread: https://www.physicsforums.com/threads/the-source-of-all-the-mind.18/
IIRC, Greg was running out of space after only about a year and deleted the first year of PF to make room for more. However, he put what he'd deleted on a disc that he would send to you (for $20 or something).
That disk is where you would find the true first thread.
... a thread dated Mar 7, 2003, started by user #2, with first response by user #7.
Too bad that the Wayback Machine doesn't have that stored circa 2003.

Didn't know there was a forum "How Stuff Works".
