Don't worry about it Irishboy, they know that everyone reads this, and most post as well (and for those of you that don't we know all about you!)
The general consensus at BA seems to be that while a lot of what is said about them on here is cr@p, a lot of it is quite true as well and you'd be stupid not to read it.
I think it makes no difference whether they know who you are or not, particularly at the aptitudes stage.
Good luck, you said you were feeling confident but watch out for over-confidence especially if you reach final board where you need that extra element, luck, to get selected.
