MC Bloodlines is a brand new hardcore SMP server that is invite only. It is made for players who want more than a normal hardcore server and who want to build real civilizations with other people.
You can only join if someone already inside invites you. Players can also invite new people so the population grows like real life and it helps keep trolls out.
The server has secret tweaks and mechanics that players are supposed to discover on their own. There are no official guides so you have to pay attention and figure things out.
There is also a built in clan and family system so you do not just spawn alone. Most clans seem to be recruiting so if you want in you can ask current members for invitation codes and learn how to use them.
