  We (the programmers) all know why a GET request that is non-idempotent is bad but a lot of books on html seem to propogate the notion that you can use GET and POST interchangably except when

  • Sending passwords
  • Sending lots of data
  • Uploading files

  How many html coders (of the type to need nms) do you know that have read the http specs ? Perhaps the error message could explain a bit about why it is bad or link to more detail on the nms website.

    I'd say tone it way down, with a pointer to an explanation of "why" online. Just explain "what."

    Your HTML form says something like this:
    <form action="/cgi-bin/FormMail.pl" method="get">
    This is an error; please see http://...
    Change it to something like this:
    <form action="/cgi-bin/FormMail.pl" method="post">

      I think it's more likely that the erroneous form tag wouldn't have an action attribute at all -- at least, the error message needs to address that possibility.
