The CSV upload makes a lot of sense for bulk uploads, but it would be extremely convenient if a person could manually enter a few e-mail addresses, perhaps on this page: https://judge.me/manual_review_requests.
Here’s my use case: I often send new products to friends. They don’t go through the normal purchase process, and I don’t want to wait the normal time for a review link to go out to them. And because there are just one or two, I’d like to skip the chore of creating a CSV file.
Instead, I’d like to enter their e-mail address and have that generate an e-mail to them with the review link.
