There are a lot of threads about this already, but you can find all of the most recent builds here. As for Nukkit, they have their own forums for these questions.
Where can I find 1.0.3... ? xD (I've just saved the poor soul from getting slapped... you owe me big time.. xD) On a serious note... With all the noobs that go about, we just have to be patient with them. Spoiler: The Noobs Even the best of us started as a noob. (Yes, I started off as a noob, believe it or not.) Compared to the PMMP-Staff, I am most defiantly a noob. So, I turned more into a idealist. I make ideas. My ideas are somewhat useful to some. And, to that extent, I am not a noob. So, before we all judge the person we all call a noob, just have a thought about what they could do in the future that could help. They could be an idealist, they could be a quick learner of code, or they could just be a plain simple noob. So, before anyone gets angry, consider what I've said. It may prove true one day...
