T'would be pretty cool, and it would mean some of the people who aint old enough to go for real BB would have a chance, because it's probs not going to last for long enough for some of us!

But there'd be so many issues with age, like kiddy-fiddlers watching, and stuff like that, so i doubt it would happen... and kids would be around more kids when they came out, so would get a lot more of the immature **** that goes with not being popular on the show, and being younger might not be able to handle that so well... that last point prolly didnt make sense, but you might get what I mean.... hopefully...
BUt there'd be other problems too... once it gets to normall BB, 18-40 year olds can get on pretty easily, but I'm not sure how well a 13 year old could get on with an 18 year old!
