Anime Hell, Midnight Madness, and Synergy in ACen 2013 Archive Posted May 10, 2013 · Report reply Hi All. I have read a few posts about Anime Hell, Synergy, and Midnight Madness and it seems folks really enjoy going to these events. I was hoping I could figure out by the coments if they are dances, shows, or discussion groups on my own, but I couldn't. This is my first con, so please don't beat me up when I ask the questions... :0). 1. What is Anime Hell? And, when and where is it? 2. What is Midnight Madness? When and Where is it? 3. What is Synergy? When and where is it? Thanks in advance.
