Phew! Panic over.
For a while there, it looked like the TDC Consultation machine was randomly rejecting emails without telling anyone.
What's actually happening is that the lone soul that TDC has assigned to the task of dealing with the submissions to the public consultation has simply been snowed under.
When each submission comes in, she checks that all the necessary name and address details are present, then checks it's not a duplicate, then updates her list of people who have taken part, and then sends out a confirmation email.
So many submissions have come in - around 1,000 apparently - that she hasn't been able to keep up, so if you haven't received your confirmation email yet, don't fret. Mind you, don't hold your breath either - she's off next week. Who organises this stuff?
