about the kernelnewbies email signature

[Chan Kim <ckim@xxxxxxxxxx>]

Hi,

How come some people's email contain the email signature shown below
> _______________________________________________
> Kernelnewbies mailing list
> Kernelnewbies@xxxxxxxxxxxxxxxxx
> http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies

.. while my email doesn't have it attached?

Are those people explicitly inserting it? or is there any option?

Thanks in advance.

Chan
