Using this page you can submit a bug report to the website author, Richard. This is emailed directly to him so that he can try and fix the problem as soon as possible.
Examples of bugs would include, but are not limited to, spurious error messages, incorrect formatting, misspellings, bad punctuation and unexpected behaviour. Please try and be as descriptive as possible when you describe your bug - what happened and what you were doing at the time.
If you are willing to leave your name or email address then Richard can contact you directly for more information if needed. This is not necessary, but it may speed up the time it takes to fix the bug.
