not all systems for allocating names are that predictable...
Ford (and therefore Jaguar, Land Rover and Aston Martin who they owned at the time) make what's called your CDS ID, which is your first initial and the rest of your surname up to a maximum of 7 letters. This made a Mr John Smith [email protected]. The next John smith who joined was JSMITH1, 10 more John Smiths later would be JSMIT11. Fine and sensible.

Except if you're the innocently named Thomas Watt, CDSID became [email protected], and Keith Nickerson became [email protected] (first names changed to protect the innocent)

My workplace used that system
I knew someone with a name like Alex Froman.

*whistles briefly*
wouldn't KNICKERS be 8 characters not 7?

You'd be in right trouble if you were called Christopher Untpieter. Just sayin.

We had a similar system at work
Which meant that Chris Thomasson got to send emails from "[email protected]"
