Wow, I wonder why people do develope sites and only support MSIE, this would
be another reason why people shouldn't use it. I'm quite happy that my
platform don't have that product.

I do agree, but if you had to go with the forking, then you could have added
one column for storing the mail id (subject or an internal id-number), and
each time a mail has been sent, you update this column, this would lessen the
risk for resending a mail to a person.

Okey, didn't know how your script looked like, could have continued a good bit
after that point.

You haven't talked with your webhotel about setting up a proper maillist, I
would think a such could work better, and you would only have to send one mail
from your php script. Of course you would need to to have a script to generate
the memberlist, but that shouldn't be to complicated. Just an idea that could
lessen the time spent to send the mail and less risk that the script will die
in the wrong place.
