OOC guilds are an awful idea, really. Nothing gets done, and you have all the pettiness and politics you would expect. The current system of people doing what they want on their own works much better. And it sounds like Rand is still fond of having guilds determine which Ages to allow, so he doesn't seem to have learned anything on that front :P That's almost as obviously terrible an idea as their "DRC Liaisons" idea was.
About Pots->Moul conversion: as I say, that will be done when we have the source code and a working client/server with source. But that would not include PhysX, as it is not open-source. So there's no point, in my view, of figuring out the redundant cooked data that PhysX stores along with the principal data, as what we really want is to convert Havok->ODE.
As I said elsewhere: Tell Rand that if he wants you to build content for free for his business, they should actually do what they said they would and open-source the tools.
