An actual forum thread with preview, explanation of items, changelog would be much better than just a get hub. Get hubs don't give much credit to making a mood look proper. And more likely to be placed in consideration for packs like FTB.
Starting with 1.2, the Christmas Update, I'll be using my own MCF thread. Until I had some new stuff added, I didn't want to make my own thread with exactly the same stuff as x3n0's version, because to me that is pointless.
Also, Github isn't meant to replace a forum thread, it's a place to host code.
