I don't think it matters; it's easy to create fake e-mails, websites, join up with online names.
So what's the point? I bet most of us know other window cleaners here in real life, and if you want to get hold of someone from here, it's not difficult. I know loads of guys from this site 'in real life'; many of whom know where I live and have been round my house at some point. So there's transparency in that. I bet many of us have 'facebook' friends from members of this site too; more transparency.
But we've had members falling out with each other, even phoning and threatening another. And Squeaky got a lot of dodgy calls at odd hours for a period, a while back.
I think the forum is okay as it is. Most of us know which posts to take with a pinch of salt, so it doesn't really matter I don't think.
