SASS number / Shooters ID

CAS scoring cannot do without the SASS number / shooter ID in its database.
We have several options:
If the shooter is a SASS member, he will use his SASS number.

If the shooter is not a SASS member, and does not have a SASS Number,
he can use a combination of his club abbreviation and Club Number instead - for example, an AWS member with the number 400 would have his ID "AWS400"

If he is not a member of SASS or any other club he can use some abbreviation of his Alias and some number, for example "Always2" as he chooses.

The shooter's ID is unique, if when entering it on the website it fails to save an entry to the event, or create an account, it means that the shooter's ID is already in use.
