[rt-users] Suggestion: use checksum digits to avoid similar sounding numbers

RT currently numbers tickets sequentially. This works well in many
cases, but, over the phone (for example), it's easy to confuse 76676
and 76767, for example.

I suggest numbering tickets in such a way that there's a checksum
digit (a la ISBN codes), perhaps something as simple as incrementing
the count by 11 each time.

A more sophisticated solution: generate the numbers so that 1 error
can be detected *and* corrected.

I'm guessing infinite sequences of numbers meeting the above property
already exist and are well-known?

We're just a Bunch Of Regular Guys, a collective group that's trying
to understand and assimilate technology. We feel that resistance to
new ideas and technology is unwise and ultimately futile.
