Talk to a person, not a form.

TryDeputize is built by one person, and every message really is read by that person. Found a bug, hit a file that would not convert, want a tool that is not here yet? Say so.

The fastest channel is GitHub.Open an issue and it lands directly in the build queue. You do not need to write a formal report: “the merge came out in the wrong order, here is what I did” is a great issue.

A note on files: never attach a private document to a public issue. Describe it instead (size, page count, what it came from); that is almost always enough to reproduce a problem.
