GangGo works decentralized which means that not a single person owns all the data. It is splitted between hundreds of servers! This leaves you with two options a) you can register at one of these server or b) you can set up your own instance.

Make GangGo even better! Fork the project on GitHub make some changes, and submit a pull request. Why? Cause we are open-source
A Ganggo is a friendly helper, good-natured man. You will understand it if you are from the South of Germany. I thought it is a match especially cause it ends in 'GO' :)
