Several times, I have attributed other users in answers that have received upvotes. This generally occurs in two ways: I am expanding on another user's hint, or the user has made a suggestion in a comment that I have edited into the answer.
If I answer a question incorporating information from another user's suggestions, I would like that user to get credit from the attribution. This would take the form of proportional reputation from upvotes to the answer, e.g., 1 or 2 points per upvote. For example, if I were to credit User X in an answer which subsequently received 5 upvotes, User X would receive 5 reputation.
In comments, we can tag other users with the "@" symbol, so clearly there is some support for username recognition in the software. Is there any way to tag users in answers and then link that attribution to reputation?
