I’ve been exploring different Markdown variations recently and had a thought on this very vein.
Would you consider publishing WriteFreely’s default combination of Markdown support as a new Markdown Syntax? (How about WriteDown? lol)
It doesn’t seem to require all that much documentation - just a spec sheet, which I think (could be wrong) would function as a solution to what we’re talking about here.
I know personally I would much rather work around your implementation than try to modify WriteFreely myself - I just need to see that spec sheet.
