How have i to send a gift? ¿Como tengo que mandar el regalo?

or send the winner the key of the game by email.
You know that you must own a copy of the game to gift it to the winner? (key, steamgift) And you can´t gift games from your library^^

Either add the person on Steam and message it to them, or send it to their email.

yes...you can see the email and the name of the winner..so just send him an email with the key..

Maybe like:

**Hello,

Have fun and don´t forget to mark the gift as received^^**
