  <h1>Example of FormMail 3.0</h1>

This example shows the use of input validation.<br>
This must be nonnull: <input type="text" name="nonnull"><br>
This should be a NetID: <input type="text" name="NetID"><br>
This should be an email address: <input type="text" name="email"><br>
This should be a phonenumber with 5 digits:
<input type="text" name="phone5"><br>

This should be a phonenumber with 10 digits:
<input type="text" name="phone10"><br>

This should be just digits:
<input type="text" name="digits"><br>

This input is not checked:
<input type="text" name="stuff2"><br>

<input type="submit" value="Submit the form">
