Hi, I'm ksedlar. I live at ET (259 Saint Paul Street, Brookline). You can get to ET by taking the Cambridge All Saferide in the evenings, by walking across the BU bridge, or by taking a Lyft Line (which is $3-4 at good times; try waiting a bit or slightly moving pickup / dropoff locations if it's too expensive). There are occasionally vans to or from ET, but the schedule over IAP is erratic.
To get into ET sneakily, you should probably contact a non-player, such as Pesto (kerberos is achester), Linus (kerberos is luh), or Justin (kerberos is jkopin). They'll probably be willing to let you in a side/back door and scout to make sure other players aren't there to witness your murdering. You can email them ahead of time and then do more time-sensitive discussions over gchat.
I will pretty much be at ET throughout all of the game, except for:
Tuesday 8-10:15 pm Tech Squares in Lobdell. Other players will probably be here
Thursday 10:30 am I have a meeting with professors Sam Madden and Tim Kraska. Please don't interrupt this meeting; killing me beforehand or afterwards is okay, though dying beforehand might make me kind of distracted which would be sad.
Thursday 7:30-9:15 C1 Squares class somewhere around building 5-2 (I always forget the exact room). There maybe aren't any other players here, I think? You can contact lzahray or blumberg for more details / for coordination killing me.
When at ET, I'll probably be in my room (Cave), which is in the basement near the back door, or Front Rooms. Note that now that I don't think I'm harder to kill than average, I will paranoia text / hide in my room if I have enough notice that someone is coming to kill me.
Picture here (I'm on the right):
My hair is kind of faded right now, but I might re-dye it purple during the game.
