Wiki outdated and some pages not working

@Sam_Horvath, the following items were on the agenda for a weekly hangout recently. Do you have any meeting notes that you could share with the community? I have seen EM Segmenter not usable after closing a scene with EMSegmenter node · Issue #686 · Slicer/Slicer · GitHub as work towards the ReadTheDocs transition.

Is a lot of this waiting on the transition to Github? Any timeline or way to move this along so that community members who are willing to update documentation now can contribute in a meaningful way?
