It's worth a shot, given that you entered though if you did win the money it would go to you and then I would assume you could transfer it and make it real tangible money for him, to show him it's not imaginary internet money.
Either way you're in on both counts, it can be hard to get people on here but once they see the reality they tend to get on bored rather quickly.
True, that would be pretty damn cool :).
Though I'd try to make him join anyway and write at least 10 posts.
Though he doesn't speak English so I hope there are some good resources here in Spanish :). (I doubt that are any in our language :D ).
We'll see. Basically, thank you for inspirin an idea in me :)
