Advanced Guestbook 2.3.2 @ and . symbol problems please help

Hi,
does anyone have this same problem. Everytime soneopne adds their email to my guestbook I get a (at) instead of a @ and a (dot) instead of a . in the email field. Can someone tell me what I have wrong in the settings or what I sho9uld do please advise. Thank you!
Joe

The @ and . are converted to them to prevent posters email addresses being harvested for spamming purposes. If it bothers you simply open up add.class.php and look for (at) and (dot) and replace them with @ and .

Thank you so much now I understand. That makes sense too. So I will just leave that alone then because I like to protect my guests. Thanks!
Joe
