[IDD #JZM-551600]: Is the SUNY NLDN feed down?

Hi Mike,

re:

Interesting.  Because you said this before, I asked David Knight
if he knew anything about the format of the data.  He told me that
it should be in the same format as what they always got.  I am
under the impression that this is the same as the format that was
resent in the IDD NLDN (now called LIGHTNING) feed, but I will check
to make sure (and let you know what I found).

OK.

Thanks for the code.  I will give it a try later today to
see what I can see.

Question:

- why the fork?

Cheers,

Tom
