When logged onto Battlenet you would type /friend 'their name'
ex: /Friend John
Chat with our AI personalities
/f a name of your friend
If you have Brood War than you can go to single player then do melee or go to multiplayer and do top versus bottom and add computers. If you have starcraft2 then you can do versus AI on single player (beta doesn't have single player) or you can go to multiplayer and play with someone against an AI. Hope this helps! :)
