How you can send a game to your friend from your computer

It all depends on the game and their copyrighted rules, if it's free, just send a link to the site, address of a store or whatever place you got it from. If the game requires some kind of a payment and you make a copy of it then you and your friend can get in trouble for it, that is if you get caught. Just use your brain and think it over before you do anything.. stay safe and out of trouble that can be easily be avoided, that is my best advice. :)

PS. There are many ways you can do this, here are just a few. You can burn it on a CD/DVD or put it on a flash drive, use MSN Messenger and give/send it to him/her.
