All very true but the best part is the "Please wait until an opening is avaiable and try again".
This means i shall be look out for what?

Someone leaving so i can take is place?
Make a sacrificial offering of a cat so the deamons of log in let me pass?

A queue at least can give us a time frame, i can deal whit that, not a totaly random event that might let me in because someone left or crashed.
