MonoMonday: Blip Names

Dollykgray is hosting this month and has asked us to explain our Blip names.

In my middle age I was so hopeless with computers that I enrolled at the local TAFE to try to learn a bit about them.
Whenever I printed something from my logon during the course it came out with a cover sheet bearing the first four letters of my surname and a number which I don't remember.

I hardly took any notice until one day another student was waving my printout around calling out "where's isbi". 
I decided that it was useful name to use for various things such as logins, email address etc and it became my blip name.

I will be hosting Tiny Tuesday this month.
Tomorrow's theme is "Flora" and the tag is TT106.
Full details are on the Challenges page.
