Re more challenge sequences needed

[N. J. A. Sloane]

Hugo P. points out that if people involved in
competing in this competition are members
of the math-fun or seq-fan mailing lists, 
then we shouldn't discuss choosing problems
for the competition in these mailing lists!

The person who wrote to me is 
"Jean-Charles Meyrignac" <euler at free.fr>
and it is fine with me if people who have good problems
to propose write directly to him!
