It hasn't gotten a lot of attention in the anglophone community (I guess that's my fault?), but geeks from around town are converging this weekend for LAN parties, code fests, role-playing games and all sorts of other stuff at the Montreal Geek Festival.
Tickets are $12 for the weekend or $8 a day. The fun is at 752 Sherbrooke W.
And if you're into board games and other non-computerized geekiness, there's also the monthly Geek Outs at Burritoville on Bishop St. The next one is March 20 at 2pm. Attendance is free.
