There's no way you can determine the email address of a visitor. You can't mail them unless they've given you their email address and then you'd have to trust that it's a real address.

Many people won't leave an email address just anywhere because of privacy concerns and the potential for spam and viruses. You may decrease GB signings if it's a required field for entries.

Why not just send them to a thank you page or use a popup message on submit? Most people get more email than they can handle and would probably appreciate a little less.

the gear guesbook has the option to auto send a thank you reply, and you can use your own words in that reply, but that happens only when they sign the guestbook and they leave their e-mail

the only way this can happen is if you use a form that the visitor fills out, and the form is scripted to auto reply a message to the visitor who fills it out.....

search google for a java script that will do that....

but as cw mentioned many people won't leave a return addy for fear of spam.

or maybe it is one of those scripts that the visiter sends h/im/er self a thank you email.
