First:
TWC is what it says on the tin, the Total War Centre
Its Center, not Centre. 
Multiplayer is not being excluded, we have actually had several conversations on that already. In fact I posted on it not 5 minutes ago in Hex.
I decided to start with the Clan stuff as MP already has a large number of people involved. Starting with Clans is a good way to drive new traffic, starting with MP would just be rearranging the traffic we already have.
Minecraft has been going for about a year, and the people managing that have done a great job so I brought them into Gaming Staff as well.
Specifically with MP stuff, about 2 years ago I threw out some ideas, and asked for volunteers to help run it. Everybody wants us to do something, I had one volunteer. One.
MP stuff will take a lot of work to get set up, more than 1 or 2 people can do. I couldnt believe all the in-fighting about rules when I proposed some stuff. It quickly got out of hand, and I let the idea drop. Even today one of the worst sections to moderate is the MP section because of all the "name and shame" stuff, accusations of cheating, dropping connection, and general foul play.
So its going to take a few guys to sit down and write up some very strict rules, set the structure up, and then get it running. Once the other 2 sections are up and stable, Poach and I will take a closer look at MP.
