If you go onto the LoL test server you'll be able to find the new ranked team section in your profile.

I'll give you some background information though as I don't think I'm allowed to post screenshots.
-You can create multiple teams for free, you can disband them immediately also
-You can choose a short tag and long name for the team; short tag is minimum 3 characters (space also counts)
-Each team has 8 Roster slots
-You can be a part of multiple teams
-Teams have a status / ranking (they are ranked after 5 games)
-The team creator sends out invites for people to join the team
-The ranked team mode is either 3v3 or 5v5 where you click to play and then invite members of your team currently online
If you want to know more let me know, Signups are open for the PBE server so check for yourself if you want =)
