We introduced two registered user type: normal and invited users.
Normal users have no chart slots and cannot upload charts to main server directly.
Invited users have 12 slots at beginning and slot number can be extended through store and events as before.
Players who have stable or beta charts become invited user automatically. And then 3 invite code will be added to thier accounts. Normal users use invite code to be invite users.
Also, when charts get stable for the first time, the author become invited user with 3 invite code. (For those who have uploaded charts before invite feature)
There is no difference between normal users and invited users in other respects.
Update to exist charts are not affected.
Please follow our twitter, we randomly share some invite code every month.
