I am looking for the stackoverflow LaTeX tag to migrate questions to https://tex.stackexchange.com/. Almost all questions with that tag have to be migrated to tex.SE. Always when I see that, I leave a comment to inform the person who asked the question that the question was "flagged" to be moved.
I know that for close votes because of duplicate questions there are automatic comments. I think a short automatic comment like
Hello [username] and Welcome to StackExchange. StackExchange has several sub-sites (like StackOverflow) that are about different topics. The kind of question you have asked should probably rather be asked on tex.stackexchange.com. Your question was flagged for migration. You don't need to do anything.
would be nice for site migration votes, too. The first two sentences should eventually only be added if the person has less than 100 points.
Would it be possible to implement that?
