// encoding and decoding of e-mail to get around spam-harvesters
// The use of a C# backend to encode the string is as follows:
//
// string EncodeEmailAddress(string email)
// {
//  return BitConverter.ToString(ASCIIEncoding.ASCII.GetBytes(email)).Replace("-", "");
// }
// 

function sendEmail(encodedEmail)
{
  // do the mailto: link
  location.href = "mailto:" + decodeEmail(encodedEmail);
}

// return the decoded email address
function decodeEmail(encodedEmail)
{
  // holds the decoded email address
  var email = "";

  // go through and decode the email address
  for (i=0; i < encodedEmail.length;)
  {
    // holds each letter (2 digits)
    var letter = "";
    letter = encodedEmail.charAt(i) + encodedEmail.charAt(i+1)

    // build the real email address
    email += String.fromCharCode(parseInt(letter,16));
    i += 2;
  }
  
  return email;
}

// display the email address in the statusbar
function displayStatus(encodedEmail)
{
  window.status = "mailto:" + decodeEmail(encodedEmail);
}

// clear the statusbar message
function clearStatus()
{
  window.status = "";
}
