These initial few weeks have been mostly planning and testing, so that once we do start to add content, everything is consistent in regards to information presented.
We do not have plans to make it an open wiki at this time. This type of information we feel is best presented with structure and organization. Call it a knowledge base if that's what you think it is, but having an open wiki where people can create any article they want and add any data they want, it would get out of hand very fast and I'd spend most of my time monitoring changes instead of producing content.
Although not complete, the link is freely available so browse it at your leisure. Just take it with a grain of salt that the appearance of its current state doesn't reflect our vision for the end product.
I've just put some TC3 !SPOILER ALERT! info up last night that some may find useful
Once you see the wiki link in the navigation on the main FTB site, you can then assume its ready for you to use
