DOTA 2 MAJORS REGISTRATION
Use this site either as a team manager to administer player invites and/or remove them, or as a player to review and accept an invitation, or leave a team. Once a player has accepted an invitation to a team, they are locked to that team, meaning they cannot be removed.

You can also look up the current roster status of a team or see the latest notable accepted invitations.
FAQ
When does registration open? Updated!
The drop period is currently open until December 27th at 00:00PST. After that period you won't be able to remove players from your team anymore, but you'll be able to add new players to your team to a maximum of five. Players in teams that haven't confirmed participation by December 27th at 00:00PST will be dropped automatically.
When will rosters be locked? Updated!
Rosters will be locked January 9th 00:00 PST, and will remain locked until after the Spring Major.
I registered my team for last season. Do I need to register it again?Updated!
Your team will be saved from the previous season but you have to confirm the participation of your team before the drop period is over. You can do this in the 'Manage a Team' tab. Teams that haven't confirmed participation will have its players dropped by the end of the drop period. During the first phase—the drop period—you can remove players from your team. After the drop period is over, you can invite players to your team until you get a full roster of five players.
How does a player become locked to a team?
First, the administrator of a team issues invites to players. Then these players can review their invites and choose to accept one of them. Once they’ve done so, the player is a confirmed member of that team and is locked to that roster until the drop phase of the next trade period.
What does being locked to a team mean?
While a player is locked to a team, the team cannot kick the player, and the player cannot leave the team.
Can a Pro Team invite be rescinded?
Yes, but only if the player has not accepted it yet. Once a player accepts an invitation, the player cannot be removed from the team.
Can a player be invited to more than one Pro Team?
Yes, but they may only accept one of those invites.
Are there substitute players?
Subs are no longer registered in the roster lock period. Teams that qualify for a Major event will be able to issue a Substitute Player invite to any one player not participating in the Major once the qualifiers for that Major are done. If they so choose, any main player from a team with a sub can then yield their spot to the team's sub by clicking on the 'Switch to Sub' button in the 'My team' tab.
CAN I RE-ADD A PLAYER TO MY TEAM DURING THE ADD PERIOD THAT LEFT DURING THE DROP PERIOD?
Yes, any available player can be added.
What if we need to make roster changes after the lock?
Making changes to your roster will cause your team to no longer be eligible to receive a direct invitation to either the Major or the Regional Qualifiers. Your team may still register and participate in the Open Qualifiers.
What if we need to change sponsors or join a team organization?
We have no restrictions on what organization or sponsor the team is part of. Those decisions are determined by the arrangement between the players and the organization. The roster lock date only imposes the requirement that the registered set of players remain together.
What happens to pending invites after the lock date?
At that time, all pending invites will be canceled.
Do we need to update our in-client teams before the deadline as well?
No, we will update the in-client teams to match the registration list.
What information is publicly visible?
Invites are private, and can only be seen by the inviter and invitee. Once a player has locked to a team, that lock is made public. If a team removes a player or a player leaves a team, that information is also public.
