Given a cell containing:

I need to extract:
reallycoolurl.com

Assuming address in A1:

=MID(A1,FIND("@",A1)+1,100)

(Presumes no domain parts are longer than 100 chars.)

.. wouldn't the 'RIGHT' function do the same thing without the limit ?

Yes, but then I'd have had to bother with LEN and a subtraction
step, I think. It just seemed easier this way, and unlikely to
cause any problems. For example, looking at the 446 spam messages
in my spam folder (Unix system) this morning and extracting all
(putative) domain names from all email addresses in all headers and
bodies, then sorting by length, here are the longest 20:

1:02pm [~/Mail/spam] 561[0] strnlnsort.sh addies | head -20

Not even the bogosity in spammers' made-up addresses gets very
long.

We could set the 100 in my formula above much higher, too.
I didn't bother, because I thought I'd be nice to system memory.
I don't actually know if an upper limit that isn't used is
committed when Excel runs a formula, however. It was just
a guess at being nice to the system at zero expected cost.

Obtw: i see some from this experiment that some junk mail from
American Express inadvertently made it into my spam pile. I
should go fish that out. I don't want it, but it's not actually
spam. :-)
