thanks Skinny, I'll give that a go,
I've just reviewed a copy of my report, and this is the bit that foxed me;
You mentioned you can send us photos or footage of the incident taking place. Please tell us more below'
so instead of submitting the (primary) evidence of whats happened, you describe a) the type of evidence and b) what it shows, and then the person reviewing your written description of your video decides if it's worth contacting you to ask for what you're describing? It's followed by;
'If the evidence is hosted online, please provide the URL below'
Hey-ho, will setup a private YT channel and use that as a double precaution - and learn how to write clickbait copy to ensure get the video viewed. 'YOU WON'T BELIEVE WHAT THIS DRIVER.... etc etc etc)
