Warning: Internet Explorer 5.0 seems to limit # addresses to 24.
Mailing to the whole list fails with "client not properly installed" message.
Select < 25 names seems to work. Suggestion: use INVERT SELECTION to make 2 lists
(for two e-mails).
I have added a confirm option that displays the List length. I have found
that 445 works, but 460 fails.
This problem does not occur with Netscape browsers.
