The NULS test-net is a very important part of the development of NULS. In order to better maintain the stability of the main-net, members of the node are expected to participate in the maintenance of the NULS test-net as much as possible. Other community members are also expected to actively participate in the test-net. In order to be as close as possible to the formal environment. This is also crucial for the development of NULS. I hope everyone will act.
Many people may need some cost problems because they don't have a server, so don't worry. Anyone of us can apply for a free Google Cloud Server, so you can choose servers from many parts of the world to maintain the NULS test-net.
You can get the cloud server for free here.
