There needs to be a better way for users who have questions marked as duplicate to contest the designation.
As of right now, there is no formal mechanism in the system for a user to be able to provide evidence that there question is not duplicated. The only option is to post a complaint on a per incident basis within meta super user. This is not efficient, and certainly not effective.
Here is a link to a clear example of the issue.
Only one piece of evidence is necessary. The duplicate refers to Win 7, the question refers to Win 8.1.
Do we not need a facility to formalize the process of an OP proving a question is not a duplicate?
