in reply to How do I add an href to email?
What you are wanting to do is make a multi-part MIME message which is too complicated to go into here. Just google multipart MIME message and there will be all sorts of tutorials for it. Basically, you can't just use HTML tags and hope they work. You have to hold the email clients hand through the whole thing and send boundaries so it knows how to render it. Keep in mind that some people (like me) don't allow HTML formatting in email and I will see the href anyway.
