Though I agree with your definition of recursive calling of a function,
I'm not sure the term recursive is limited to functions. However maybe
repetitively would have been a better choice.

To clear up some things for some of the other respondents, the page gets
called several ways.

1) The initial GET domain/page.php which includes() an intro and list of
links.

2) A second GET from one of the links:
<a href="<?php echo $_SERVER['PHP_SELF'] ?>?whoDoYouWantToContact=John">
which then includes() the HTML form.

3) A POST from the form:
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" >
which then includes() a process the form script and an acknowledgement
that the data was received.

Denis, my testing confirms that you are correct, placing the
session_start() on the core page does not produce errors on subsequent
GETS or POSTS. Which makes logical sense, but seemed to conflict with
the manual. Thanks, helping clear that up.
