Well, that's the point I was trying to make, i.e. it shouldn't be a custom project, it should be standard. In fact, the whole notion of allowing people to publish their address as default is wrong. It should be the other way around, i.e. they should have the choice to 'show' their address - if they're that stupid
Any self-respecting classifieds site, and I include Ebay, hides the seller's address for good reason. It's irresponsible for any site these days to show people's address as default.
When we're talking about places in the public domain such as restaurants, hotels, shops etc, then of course the address is an essential piece of information. But for regular people selling things, or renting out their rooms, it's not a wise idea and for this reason it should be hidden by default, with the option to show if they wish.
