Effective immediately, anyone registering will be required to complete the Location field.
Now, there's a rub to this. In order to make this happen, the Location field is also now mandatory if and when you update your user profile. If you already have a location entered, nothing will change. If you have no location entered, and want to update your profile, you will have to complete this section.
You do not need to be specific on location. The nearest city/town etc is fine.
Let's try it for while and see how it works out.
