Mrs Daysleeper subscribes to a parenting website, recently they have had a problem with "fake" parents , strange I know. The solution was to get parents to send in a picture of their babys holding a bit of paper with the username on it. Anyone can still post but only those who have carried out this "verification" will have a kind of signature thingy.
So how bout a photo of your aeroplane with your username written in the dirt on the gear doors or something...
