Thank you for organizing this. Oslo is my hometown, and I will definitely be there if it coincides with a trip home. I'll find you on freenode later and send you some information about possible attendees from a previous attempt at organizing an Oslo meetup
After some deliberation, I realized that an Oslo meetup wasn't going to happen by itself, and after my somewhat abortive (and way too late) attempt to organize a PI day HP:MoR wrapup meeting, I decided to just do it, and announce that it's happening, four weeks in advance.
Please add yourself to the coordination timetable.
Here are the possible locations:
UiO Science library (only open on the friday).
Hackerspace-Makerspace.
I'd prefer to meet up at the Library, because it seems like the perfect place for a LessWrong meetup, and it's open to the public until 10PM.
However if it doesn't suit enough people, timewise, then I do have 24/7 access to the hackerspace as a backup plan, and there is food nearby.
Please respond with any suggestions as this really is my first time organizing anything, I am aware of the guide.
Edit: Unfortunately That Social Media Site has locked both of my accounts, so contact me either via freenode (FourFire), PM here, or email me.
