Holy Molly, I
resurrected Three Millionth User!

That was yet another unexpected turn of things, as I (and probably others too) believed there are few chances to see the respective user among us again.
After all, I think it was a good idea to create this topic:
- a mystery
was solved -- thank you, theymos, for clarifying that
- Three Millionth User is active again -- or, at least, for a while
- everybody found out
for sure that he was not an ordinary newbie
- maybe some found more answers to possible questions they had
- I vouch for Loyce's
four hundred fifty nine thousand, eight hundred thirty sixth user and, if I may, also for the one million two hundred eighty-five thousand seven hundred ninety-seventh user as well

Well, all being cleared out, I think I can lock this topic now (I will do it in 24h from now on). Thank you all for expressing your opinions here.
