I forget about the Eudyptula challenge, I am going to start with that
and I will make an agreement that you guys.
Until I complete all of the challenges correctly , I am not allowed to
sent out any more patches. If I do I don't
want any response what so ever , no matter how hard I plead. If this
is a deal , Greg and others please reply.
Thanks for the Help and I still don't known how the hell you haven't
given up on me yet,
Nick
