User enters email, download link gets delivered

Hope someone can point me in the right direction. I am looking to offer some software on my site for free where the user enters in their email address and then they receive an email with a link to the download. This link would then expire after a certain amount of time.

 

Hoping someone has any ideas?

 

do you mean after they have uploaded an item or for a download off your site.

 

For a download off of my site.

 

oh ok then i dont know. sorry

 

you mean when user want to download something they must first enter their email id so the download ink will be sent to their inbox?

 

Yes, that is exactely what I am looking for.

 

I'm interested in this too. Thanks a lot.
