Why don't I see an edit button under questions?
I am successfully able to Edit some questions. But some questions like this like , I am not able to edit this question. why so ? In that question there is no link of Edit.
Someone else (Java again!) has already suggested an edit so it blocked additional suggestions until it's approved or rejected. See this here.
It was proposed 13 minutes ago and approved 4 minutes ago, so while in the queue people with less than 2K reputation won't see the edit link indeed.
