Hey Darnel,
Correct me if I'm wrong but am I correct in saying all you are wishing to do is display a link that says 'Contact' that when clicked open up the users email client with a new email message to the email address supplied from the DB?
If so, all you need to do is replace your code with the folowing (not tested):
if(!empty($myrow['email'])){
echo "<a href=\"mailto: $myrow['email']\">Contact</a>";
}
That should just display the word 'Contact' as a hyperlink that when clicked opens up the users email client.
As the previous posters have stated, the other option would be to create a form that the user fills out and submits, then create a php script that forwards the data to an a specified email address. Straight forward enough to do, let me know if you need any help with that.
