What Cap.... I can't use slang? You seem to all the time. I don't think apparently was meant to be slang do you?
nah.......use it all you want. but if you're going to correct someone else's "slang" then it's generally best to avoid using it yourself.
i use it all the time, except when i'm correcting someone else's.
i also never capitalize, simply because i type using "hunt and peck", and it slows me down too much.
