I honestly don't think it would be much work at all.
1. You add whatever presentation is required to get the latest amendments to the laws of the game across as the very first part of re-affiliation, (before any data entry) on Whole Game System, thus everybody who completes affiliation via whole game has seen all of the changes.
2. The 5% max who don't use Whole Game are contacted by whatever means possible to organise facilitation of the required additional education required before they can apply for re-affiliation.
This is known as 'Gateway Training' - the training has to be completed as a mandatory before the next step can even be attempted.
For point 2 an outside company could be used to process if CFA don't have resources - approximate cost £2 per contact required.
Working on the previous example of 1407 referees in London, 5% of which don't use Whole Game (although I suspect it's actually a lot less) equates to circa £140 cost to the contact centre.
Anybody know the typical percentages of non Whole Game users in their county?
