Enter email to download content

[seedaudio]

Hi, I"m in the middle of setting up a webshop here, but in the mean time want to direct people to a landing page. This is actually the password page which tells people things are coming soon. I've managed to remove the 'Enter Password' on the top right for now. 

What I'd like though is to add a download link to a file but in order to do that people have to enter an email address. 

Not sure how I'd do that just on this page. 

Any ideas? 

Cheers
