It's a great idea, only thing is I am about to travel abroad for several days and will have limited access to internet + calls from abroad. From the thread on Pepipoo I now understand that with the double yellow line being there my chances are very slim and I could appeal on a technicality (the 14/28 days being counted incorrectly on the PCN). If I wasn't away I would give it a go, but it's too much of a risk to miss the NTO in the post. Luckily the discounted rate is only £35, so on this occasion I can count my losses. Thanks so much anyway to help me discover this new forum! All in all a positive experience!
