How to report a figure that disagrees with its source, suggest something missing, or ask about how a calculator works.
Write to pharaujo@gmail.com. It reaches Paulo Araujo, who writes and maintains the site.
Corrections
The most useful message is one naming a page, a figure, and the source that disagrees with it. Rules on this subject change often and some of them are being litigated, so a page that was right in August can be wrong in October.
What this site cannot help with
Your own account. Only your servicer or your aid office can see your loans, your payment count, or your plan. This site has no access to any of that and would not want it.
Personal advice. Nothing here is financial advice and no message will change that.
