I was there as well, but since my train didn't leave until 05:50 I've only just got back home now. I was able to record the audio for it and can provide it if you want, and can tell me the best way to do so (I've not done this before).
I was able to ask a few questions at the signing part as well but I'm really tired right now and some of the answers are quite detailed, so you'll have to wait a bit for me to transcribe them.
Also, my first post .
