Here's the tentative index for Dangerous Dungeons. Nearly everything is already written except for the chapter on planar adventuring and a few monsters and spells. We're still looking for artists willing to contribute and someone familiar with constructing form-fillable pdfs for a few supplemental extras to include for the book online.
Layout is still not complete, but it looks to be somewhere in the 500 page range. For those wondering, everything will be designated open content with proper accreditation.
