As to why, that's simple. WWC2 was in limbo for about 12 months, but now is back in full swing. The locked threads generally dealt with either the original WWC from 1.09 or my original thoughts for WWC2. While some of that which was posted may still hold relevence, most no longer applies.
So a clean start with a whole new range of threads, while keeping the old ones locked away for reference if the need should arise.
Look forward with chatting with anyone willing to give the mod a good test out.
