As its generally a one off maybe access to the "country flag" menue in options was not as accessible as I thought..
Come on Kevin you can do it...
My memory may be at fault again but I thought that there used to be a 'courtesy flag' selection point, provided so that a member could indicate in which country they were currently residing. (That sometimes confused new members who decided that the flag against their name was to indicate where they were born, rather than where they were located).
I certainly remember selecting the Union flag and seeing it displayed against my name for many years but it disappeared in one of the many system updates, along with my avatar. However subsequently I was able to find the facility for adding the avatar but couldn't find the 'courtesy flag' facility.
