This instance used to have open registrations, but it seems a lot of spammers, trolls and bots found us to be an easy target because of this. So we have switched to requiring an application to see if things improve. We didnt really want to do this, but its much better than angering the rest of the lemmy community.
So please write a few sentences about yourself and why you want to join the lemmy network. You will get an email when you are approved. :)
