Hey jacalata, thanks for pointing this out. I've reproduced the issue as best I can, and AFAICT you should see a link on that page which says "Change you answers".
Clicking it should display a list of the answers you've chosen, and the top one should be your location. Clicking that should let you change your location.
If that doesn't work, drop me a line at jcrompton@infoxchange.org -- I'd love to get enough info from you to properly reproduce the bug so we can fix it.
I don't think it's a bug, It took me a while to realize that "Change your answers" is how I change my location too. Perhaps the wording could be changed to make that more clear :)
Oh really? That's unexpected - I'll log a bug for this right now. Thank you so much for reporting that, we rely heavily on the input of others just like this.
