1) I have no idea how to register a name to Teamspeak, so when I join the channel i'm actually the admin.

2) I downloaded a server, been messing around with it. I can join it, but none of my friends can. They all get errors. I tried both ips with the ports that show up when I right click on the server icon in the menu bar.

Any help with these would be very much appreciated, i've been trying for like an hour now
