Although the Nether biome is a hot topic, remember that items still should be put in their proper categories, even if they are Nether related. Please read the pinned post on creating biomes and dimensions. Please put items for the new Mountains and Nether Updates in their proper categories. Remember portals are structures, that includes Nether portals.
