Sorry if I'm wrong but I think it's a feature of games and not kong itself so if I'm right then a lot of mmo games in kong have a quest and a button that would allow one to invite your kong friends to play the game. I'm just hungry for some new quests
also now that BC is on the front page in kong I assume that the developers are confident that they will keep the new players after the ad expires so i'd like to invite my friends in addition to the ad as to work as an endorsement. Cheers!
