Is your username still available ?
I think for user that using a lot of web service , thinking of a username should be something difficult , because on service A , you might be able to use your favourite username , but on service B your favourite username might be taken. It’s quite messy to use different username on different service and this is not recommended if you care about personal brand.
So what i found today is a site which allow you to check your username still available – usernamecheck.com
i did a compare between knight and imknight
as you can see , imknight is still available for most of the service, those taken should be done by me too, knight is consider too general and among most of the service, knight has been taken. Still thinking about what username to choose ? this service is recommend for you.
