I'll leave the extra competition schedule up to someone else, since that's not my area.
However since servers is my area, I'll answer your Nazi Zombies question.
I did look in to setting up a server at the LAN for you (as I said I would
), however, I didn't get the chance to get it completely set up due to the comp + server team being quite busy. The busyness was compounded by myself being sick from exhaustion (busy few days and not much sleep friday night) on Saturday evening. So apologies for not getting the server up.
However!
Since a few people asked for this during the LAN, I'll make sure there is one next LAN, along with plain CoD5 servers.
On another note, you are more than welcome to run your own servers, be it a listen server (ie, you play and host in-game) or a dedicated server (running a seperate program on your PC). Not only do we allow this, but we encourage it. Doing this has the added bonus of that if you wish to change level, game mode, what not, you don't have to come up and ask us.
--Edit--
Also, now is the best time to request other servers for the next event! =D
