Sadly, due to a change in the wikispaces hosting policy, the GregTech Community Wiki is no more
The basic progression idea of Copper+Tin -> Bronze -> Steam Machines -> Steel -> Electric Machines has remained the same, but after that it gets a bit more complicated, as the number of electric machines has exploded. :wacko: The other main progression change is that all vanilla Tools are now extremely weak, and have been replaced with an array of automatically generated Meta-Tools. Meta-Tools can be crafted out of just about any hard metal added by any mod ever (so long as Greg's heard of it), and are roughly comparable to normal tools in durability and speed, but have the odd quality that they effectively force Adventure Mode (you can't break a block with a tool that's not designed for it).
The Official FTB Wiki is our new home, as has been said, and it does contain useful information.
