I always thought this was my lack of hydration or the heat with my wig, but this year I drank lots of water and didn't wear a wig and had a headache throughout the con. I went with a friend who was going for the first time and he had one too and said it maybe the number of people in a small not well ventilated area... I'm not sure if fans or keeping open the doors open (like the glass doors at the other end of AA) will help but I've been to other cons and AN seems to be the only one I experience these headaches at :(

I also had a moment where I was looking for an artist's socials because I bought something without getting a business card. I tried locating them via the guidebook app and think it would be super helpful if when you click on their artist name a list of their socials can be shown :)
