This is just a heads up for when 1.8 is released. We will be starting a new world, but not until a beta build of craftbukkit. This is expected to happen around the end of April.
When we started running a new world for 1.7.2, we did so too early which left us with a world that was not generated properly. Jungles and ocelots are almost non-existent. We will be patient to avoid this sort of problem for 1.8.
That said, many thanks to all our players for sticking with our current world despite the issues. In fact, there hasn't really been any complaints about hard to find jungles, just casual comments.
