Did you get a weird crash? If possible, hit the 'Upload Traceback' button to notify Spiky and send him the relevant code links, but you can also post about it here.
Did a graphic fail to show up? Let us know where you were!
Did the plot seemingly contradict itself because you TOTALLY were holding the Orange Prognosticator in your hand but now the text says it's buried in the desert? Tell us what went wrong - use rot13 if necessary to hide spoilers.
Really I'm just blathering to say "yes, post bugs here".
