I've tried on multiple occasions to submit some information to FreeDB, only to get error messages about how my entry in one or another field is not in the right format, etc.

I don't feel passionate enough to make changes to how I have configured my database so as to meet the FreeDB requirements.

So I have this suggestion: Instead of a mere error message, show a window with all the data about to be submitted, highlighting the items that need to be modified. The user can then modify the items as required on that window, and submit the information--without having to modify the actual database record.
