Welcome to WebmasterWorld Guest from 188.8.131.52
I would like to know how to set something like that up. Also can you automatically email them the ebook?
I hope this is the right forum for something like this.
Also, forcing someone to type in an e-mail address before they proceed is never going to work unless you have some sort of verification e-mail sent. Otherwise your mailing list is going to have quite a lot of fake e-mail addresses I`m afraid.
Hope that helps.
