Here is a brief explanation of the fields:

'Page:' identifies the page number in the Wilson Dictionary where there needs to be a correction
'old:' If one of the enumerated headwords printed to the left is spelled wrong, put its paragraph number and the old spelling in the 'old' field below; preferably, use the HK transliteration for spelling the word.
'new:' is the correction to the old text; again, we prefer you to use HK transliteration here, as this is the 'native' transliteration of the digitized Wilson Dictionary.
'com:' indicates nature of error (e.g., 'spelling'.)
'you:' your email address or name, if you wish to give it.
