I have received several complaints of reviewers who had typos in their PayPal email addresses. Since this cannot be edited, they can't correct them. While I understand the reason for the no editing policy, I recommend giving a small window for editing the email address, say, 1 hour. This way, those who had typos in their email addresses can correct them.

Here is the link to the preferences tab containing the PayPal email addresses. https://forums.onlinebookclub.org/review-team/preferences.php
