I let it find my location and now I can't change it, so I keep getting "Sorry, I couldn't do this search.
Could not find a location matching "Seattle, Washington""
The service is not currently live in the US, we're an Australian based organisation as is our target audience at present.
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.
Thanks!
