Today it happened again that I wanted to post an answer to a question, which all of you know can take some time to write, but some minutes ago the question had been deleted by the owner.

For the (currently) few who can see [the deleted question][1] which IMO is **on topic** regardless of the OP stating:

> I have the following code, I know it's inefficient because sporadically it throws an OutOfMemoryException due to the ToArray() call".

I had been tempted to hit the "undelete" button but hadn't been sure **when** to undelete a question.

When should one undelete a question which was deleted by the owner of that question?
