Before leaving a rating, here or elsewhere, please get in touch with me to see if there’s been human error. I’ve been receiving too many emails with users first rating, then asking me for solutions and after it’s been fixed, asking me whether they can rollback their rating. These premature ratings really hurt authors, including me.
So please contact me before rating the item so we can fix any issues together. Also, feel free to ask me any questions you may have regarding the code before purshasing to avoid mismatched expectations.
