This change has been done with very little warning as far as I can see. This afternoon, just when I needed urgent access to NOTAMS, it won't let me in until my registration has been accepted. What a wonderful contribution to flight safety.
I have written to NATS to ask why they did not continue the old service until we have had a chance to sign up to the new one. The Met Office did this when they recently upgraded their website.
Is this the attitude we can expect to users of NATS services?
