Is it possible to modify the input format for dates in front end form? From other threads and my own tests a date field needs to be input in the format of 10/15/2012 (mm/dd/yyyy). But that's not very "British", is there any way to modify it?
Paul, when I change the Locale setting to British English (en_gb) within the database, the Post Date field's date-format changes to dd/mm/yyyy.

In DB: databaseName > craft_locales > Change "en" to "en_gb"

Let us know how you get on :)
