I'd like to give my opinion on this. I'm Dutch but live in Belgium and together with some other Dutch and Belgians I'm a location hunter, trying to get notes from as many locations as possible. A location is in my opinion a city, a village or even a hamlet. Mostly we only use a separate name for a village or hamlet when it has it's own town sign.
It the case of Gent as stated above, Gent is the name of a city and a municipallity. The city of Gent consists of several parishes, i.e. "Binnenstad", "Stationsbuurt-Noord", "Stationsbuurt-Zuid", "Brugsepoort-Rooigem" and many more (source
official site of city of Gent). The municipallity of Gent consists of the city of Gent, plus a lot of "Deelgemeenten" , see
wikipedia: 9030 Mariakerke, 9031 Drongen, 9032 Wondelgem, 9040 Sint-Amandsberg, 9041 Oostakker, 9042 Desteldonk, 9042 Mendonk, 9042 Sint-Kruis-Winkel, 9050 Gentbrugge, 9050 Ledeberg, 9051 Afsnee, 9051 Sint-Denijs-Westrem and 9052 Zwijnaarde. These are all different villages, they should have their own town signs (I can't check as I don't live near Gent).
Some users are extremely precise when it comes to locations, I'm one of them. Others use i.e. 9052 Gent for Zwijnaarde. It is impossible to sort out all these locations by postal code as some villages have the same postal codes. On the other hand I wouldn't like to see all profiles merged to Gent as I love to check out profiles of smaller villages, see if I'm the first EBT'er in some small town etc.
Another difficulty in Belgium and Holland is that some municipallities seem to dissappear and are swallowed by bigger cities/municipallities. So it could happen that one town within a municipallity will be part of another municipallity some years from now, and another village in the same municipallity goes to another municipallity. Believe me this has happened before. Wouldn't it be hard to sort everything out then!
It is a difficult situation and opinions vary on this subject. I would propose that the Belgians sort out the way to merge Belgian cities, Germans stick to their German cities and we Belgians don't complain on the way German cityprofiles are handled (and I know not every Belgian agrees on how it's beeing done in Germany) and vice versa.
Just my two €-cents...
