Possible Duplicates:
Display where has the question been migrated on the title instead of just [closed] (this q isn’t closed!)
Favourited, migrated questions appear as having no answers
If a question has been closed in stack overflow it is not possible to know without opening the question if it was a bad question or a good question that has been moved to one of the other sites.
I suggest that questions that have been moved have a [Moved] tag put next to the question, and possibly that that tag be clickable and take you straight to the question in the new site.
