Is there a way to undelete a question? I deleted it, and now when I try to re-post it, I cannot as the system recognizes it as a duplicate question.
Ask a moderator ;-) I undeleted your question for you.
I don't believe you can do so yourself, though, because the system doesn't let you see deleted questions. If you could see them, I think you would be able to undelete them. (Something to look forward to when you get 10k rep perhaps?)
