Hello everyone,

Does anyone know what "handle" means such as below link:

Can anyone please tell me what should I fill within this field?

Thank you very much in advance

I think it's a user name (like optics.tech)

Handle, is a username in this case. It's what you are known by.

Generally only used in radio communication though.
