We get a lot of duplicate questions from new users. We want to mark those as duplicates, but not scare off those new users. Right now, the automatic duplicate message is neutral, but rather brusque. This can be off-putting.
Could it be changed from "Possible duplicate of [existing question]" to:
This question may be answered by [existing question]. [Questionposter], does that question cover the same ground? If not, please edit your question to reflect the differences.
or something similar?
