The fastest way to contact me if something breaks would be to ping one of my underlings at #HorribleSubs@irc.rizon.net (use the chatbox on the right).
If that doesn’t work, try to tweet me @HorribleSubs.
If you don’t want to make a twitter or don’t have one, e-mail me at guildeldh[at]free[dot]fr.
I’m usually pretty good at responding within a few hours.
