If you hover over your name at the top of the screen one of the options shown should be Personal Details. There should be the option to change your location in there. Let me know if that works, if not I'll have a look in the permissions. Rebuilding search indexes at the moment so can't access that side of it for a while.Sorry, being a biff again. I've moved back to the UK from Germany and I want to change my location.
I've had a good mooch about the settings and my profile, but can't figure it out.
