Alien communities are a different way of connecting with fellow members. For example, you can schedule events whenever you want and just post them so others know. It would go like this: You are going to the gym and it would be cool if someone joined you; so, you post the date, time, and the location and everyone will get a notification immediately as well as when the event starts. This way, you give yourself the possibility of interacting with others while doing things you were going to do anyways, and the best part: it's without sacrifices or compromises. Of course, like any community, there is the option to chat, upload pics and vote on surveys to see which event is more exciting for its members. Communities can be created by anyone and can be public, invite-only, or private.
