If you read the descriptions, you'll see that a sequence should be 
marked "nonn" if all the terms in the database are non-negative, even 
if later terms are not.  So the current keyword is correct.

http://www.research.att.com/~njas/sequences/A059571 has the keyword
"nonn" but if I understand the conjecture correctly, then the fact
that the conjecture has been disproved shows that it's not "nonn" but
rather "sign" ... eventually.  I doubt we'll ever get enough terms
listed (more than 10^16?) to find the first negative term in there.

So how should it be labeled?  I think "sign" even though all the given
terms are positive.
