I just read about this in Freeskiers new buyers guide, and think once it comes online in September, we should provide a link to it in the Resources section and use it as much as possible. The Regionals are great, but often times it is difficult to find the information you want or get the information you want out of an NS member on short notice. The wiki will be a good way to keep infomation freely shared about your mountain, because maintaining a thread is a PITA.
Check out more information at this link:

It is possible that we could do something like this as a part of NS, but until we do I think we should use this.
