Currently, Wiki-mage is getting a bit more done.
The Players Handbook is about 65% complete now. It needs the large block content yet. Spell descriptions, appendices, etc...
The Dungeon Masters Guide is still only just begun. On my own, I will probably work on one book at a time. In which case, the DM Guide won't get worked on again until the Players Handbook is completed.
I just have placeholder pages for the other 5 books right now.
Still welcoming editors to help build it up.
