v1.2 : The Hub
Every network needs a heart, and ours got one in v1.2: the Hub server.
From this point on, the Hub became the central landing point for the network. It's the first thing you see when you join, and the place you return to when moving between game modes.
The Hub itself was built around a custom lobby world, originally a licensed map that was then heavily modified by Jamie and various community members over time. If you're curious who contributed, there's a credits sign underneath the central archway. Go have a look.
v1.3 : Creative Mode
With the network taking shape, it was time to add a place for people to plan their builds. v1.3 introduced the Creative server, a creative mode environment with full WorldEdit support.
