You registered into Unifi Community. And then you realised that you have chosen the wrong username and you wish to change it. By default, once a username is set, users are not allowed to change it. So how can you make an amendment to it?
Fret not! Just pm to @Community_Admin with your 3 usernames of your choice and the change is subject to availability. Just remember not to put in anything related to your personal details (i.e. full name, contact number, IC number etc).
Once the username has been successfully changed, you will be notified via messages box in this community site, so do check your inbox as well.
