Reasons for duplicate user registrations

If you are using a shared server, duplicate entries may occur.
The reason for this is the way shared servers work.

How the Shared Servers Work

A shared server is a form of rental server in which one server is shared by multiple owner-managers.
Imagine renting a room in a condominium, a "shared house" service where one server is shared by several people.
So, duplication of items may occur when registering users.
 

Duplicate conditions and how to deal with them

login ID

The login ID must be unique.
Login IDs used in other owner-manager environments cannot be registered.
The following letters and symbols can be used, so please create a mixture of numbers and special characters to prevent duplicates.

Character and symbols that can be used
Half-width alphanumeric characters (a to z 0 to 9), special characters (! " # $ % & ' ( ) * + , - . / : ; < = > ? [ \ ] ^ _ `)
 

display name

The following letters and symbols can be used as well as login IDs, so please create a mixture of numbers and special characters to prevent duplicates.

Character and symbols that can be used
Half-width alphanumeric characters (a to z 0 to 9), special characters (! " # $ % & ' ( ) * + , - . / : ; < = > ? [ \ ] ^ _ `)
 
*If you are using Ver. 2.20 or higher, you can duplicate the registration already made in another owner-manager's environment.
 

E-mail address

To deal with duplicates, you can use the "+" sign to create an alias for an e-mail address.
Please enter "+00" for Gmail or "++00" for other than Gmail before "@".
Note that all mail will be received at the original e-mail address before the "+00" is added.

Example.
0000@learningbox.co.jp・・・Original E-mail address
000000++user1@learningbox.co.jp... ①
000000++user2@learningbox.co.jp... ②
All e-mails received in (1) and (2) will be sent to the main source "000000@learningbox.co.jp".

*If you are using Ver. 2.20 or higher, duplication is possible under the following conditions.
　In another owner-manager's environment,
　E-mail address registered as a user account ・・・ Duplicates OK
　E-mail address registered as owner account ・・・ No duplicates
