Kulli, those words of wisdom lack a significant factor. We can't read your mind, so if you could provide detail of how it might be improved in your opinion, we'd all be a lot wiser...
Making it more easily visible(next to post count maybe), finding some sort of incentive for people to fill it in, or at least trying to make it the done thing. I'm pretty sure it's all been discussed before. At the moment it's a nice idea bu nobody uses it at all. Not saying it'd make all transactions perfect, but it'd give a bit more of a heads up on any chancers.
