have you looked in your 'my questions' list in your profile? If it posted successfully it should be in there, if it didn't submit properly because the site was sooooo slooooowww then you'll have to try again
PS: I remember seeing a question entitled 'Is it legal?' appearing in the 'Unanswered questions' pane, but clicking on it resulted in a 'Page not found' message. That's yet another example of what I was referring to in the post I've linked to above.
