I just tried to flag this question on AskUbuntu as a duplicate. However, due to it having a bounty on it, I cannot. I just get this error:
Even if the general StackExchange policy is to not close questions with a bounty on them, it should be possible to at least mark them as duplicates and add the flag somewhere. I don't think it's reasonable to have to wait 7 days just to mark it as a duplicate.
In 7 days, I'll have forgotten about this question anyways, I'll forget to mark it and it won't show up as "possible duplicate", just as a "linked question".
EDIT: To clarify: I do not necessarily want to vote to close the question. I'd just like the box to appear just like it does on this post:
And as far as I know, "flagging for moderator attention" does not do this.
