Startup Idea : Tinder for parties

This is an app that would allow university students/ youth to post parties on a platform that would then allow members to swipe depending on the distance from the party. The host would then swipe people who they would be willing to provide entry to. It would be linked to facebook accounts with a rating system based on past feedback and also have functions to dictate the amount of alcohol, byo etc required on entry to the party. There would also be a function to allow people to swipe in groups with their friends.
