Change term "Address" => "Location"

We have noticed that many cases people are filling the "Address" field for proposals but they are not writing a proper proposal address there. Instead, they write either their email address or their own home address there. To fix this usability issue, we suggest the following: - Change the term "Address" to "Location" - Change the checkbox "Has address" to "This proposal has a location" Some people have suggested that the address field would not be a field that the users need to fill but instead, it would be a map where they can just click the position to. This would possibly make it even clearer that they need to pinpoint the location for the *proposal* itself.
