I would give back all my Envato earnings if I could be 18 and go to college again, trust me
Even many top selling files have a lot of 1 star rating, which cant be good for authors. Introducing comments for ratings is a good idea, but this would needed to be moderated a well, because whats the point of stylesheet is missing, not a wordpress plugin comments if they are invalid.
We need the current comments system we have converted into some kind of forum type system, including all the comments made so far converted into forum threads, and all that being searchable and sortable in any possible way, thats what we need.
You should contact the author directly in the comments of the file you bought.
Congrats, you have some cool files!
Its best to ask these questions the author directly in the comments where you bought the file.
