By the way, Andrew, in the webinar I see that in the Location settings, you left the field 'Nominatim email to identify requests' empty. But on the OSM page on github it says:
'If you are making large numbers of request please include an appropriate email address to identify your requests. See Nominatim's Usage Policy for more details.'
So if we had to fill out this fied with an email address, should we enter whatever email address or should that email address be registered somewhere on the OSM server or website first? Thanks
