The webform above suggests that counties of the United Kingdom include places such as Abuja, Akita-ken, Alberta and BadenWurttemberg as well as Argyll. (The full list is much, much longer, of course, and ends, somewhat weirdly non-alphabetically, with Zakinthos, Odense So and Pennsylvania - bet the last two won't like being an afterhought!)
To top it all, in the form above there is also no way to pick "London" or "Greater London" as your county, because neither of them appears in the dropdown list. Nor do individual London boroughs, before you ask. Very annoying.
I suppose I could always go for Xanthi as my county, just to put something down.
Or Uttar Pradesh, or the Vale of Glamorgan, Thessaloniki, Kelantan or Cleveland!
Usability police, where are you when we need you?
(Also on the webform front - funny/weird use of radio buttons; and dealing with multicultural names on web forms.)
