Can I add "Possible duplicate" text to a question which is not closed as duplicate (yet), or should I wait until it's closed and then edit it?
Also, what happens if I add links to possible duplicates and later the automatic possible duplicates bot finds this questions? Will it add the same links or will it spot that they're already included (even though I don't use the same formatting for the possible duplicates text (e.g --->
)) and will leave the question?
