@ProfM Thanks for pointing this out. Now that you've made the flag, the mods will see it and fix it. You were right to come here though, since having a question "flagged" can sometimes be bad for the user's lifetime StackExchange record. The fastest way to solve this problem though, is to edit the question (which now you have enough rep to do freely!): remove the
dira-semimetal tag and replace it with
dirac-semimetal.
