What do you think about it? Do you have any wishes before we try it?
First of all, thanks for your dedication, it is great to see competitive spirit
Personally, I think that a new NIC is a great idea, especially the amount of players per team is pleasant, normally it is difficult to get enough teams that are large enough for a competitive gaming.
About maps, just message a map admin for some hints, however I do think that the map design is not that important for NIC as it is for usual CW's, so 2-3 maps are also fine.
In my opinion you can start the event as soon as you wish, just don't forget to approach an admin for moderator rights.
What do you think about a reward for the winner? Maybe an unique signature or something similar?
