@andrecas: most of these small changes are intentional - word spacing, periods, missing prefixes or suffixes, missing IMOs can all affect search functioning - especially for those without IMO numbers.
Names which are in all-lower-case ("queen elizabeth") are not acceptable and will be modified. Names with capital initials ("Queen Elizabeth") remain acceptable, though in the process of bulk review of a particular ship they may be changed to the generally-preferred upper case ("QUEEN ELIZABETH").
The work of Category Admin and Photo Correctors in improving the functionality and consistency of the site is much appreciated.
@Allan: certainly shouldn't have happened, and I am assuming a mistake/misunderstanding. I am sorry about that.
@Robert: I'll post here again when I have found out about this.
