I would really appreciate it if you could remove the pre-formatted text from your post. It makes it unnecessarily cumbersome for people to read a single long line of text that they have to horizontally scroll through.
In my opinion, the Q&A section is a very powerful and versatile section of your gig that you wouldn’t wanna leave blank. Sometimes, it is not really possible to cram in every little information about your gig into your gig description. In that case, the Q&A section can come in very handy. Even otherwise, you can use the Q&A section to reinforce/stress on some minor yet important details that some buyers might miss while going through your gig description. Obviously enough, it can also be used to answer buyers’ most commonly asked questions.
Due to the above-mentioned points, I think a well-designed Q&A section would make a significant difference to your gig and that it could help sway some buyers into purchasing your gigs.
