Make your own default community

Hello everyone, we are going to do 2 important tasks.

1. When someone singup, we will add them in your own default communities where you will operate and update your end users with posts and announcements (will add settings though) so make sure you have your own central community is ready

2. We are making a nice, demo and dummy community which we will give your and our users for 24h in exchange of a valid email

What you think? Anything you want to add?
