Don't see a need for you to make these comments, some 12/13 year olds may not feel comforatble around the older teenagers. That's all. Just leave them be maybe? Its a harmless thread and I don't see why negativity should be brought into it.
anyway I won't start an argument, I just want to say this is a lovely idea and I know this is somewhere my younger sister would come if she felt a bit out of place with the others, so once again, good idea
