Have you found any errors in Definitive Edition? If so, please report them using this form:
There are very few reports of errors here. It is, I think, actually possible that this is because the current draft of ArMD is exceptionally clean, and contains almost no errors. (It is derived from texts that the community has been working with for decades, we had months of discussion here, and then @callen and I went through it all again. We could, conceivably, have caught almost everything.) However, I do not believe that.
This is the last chance, because layout is finishing up, and then we will make the final corrections before sending the book to print.
Thank you!
