The warhammer tag has a number of questions that are asking about a very wide variety of topics. They range from Warhammer 40,000, the Warhammer game rather than a tabletop RPG, and questions about Warhammer Fantasy. We already have wfrp, wh40k, rogue-trader, and others that cover most of the Warhammer universe.
Given this information, should we remove the warhammer tag because it is so generic?
