Hi, welcome to Warehouse 13 Wiki! Thanks for your edit to the Artifact:Johann Maelzel's Metronome page.
Hello and welcome! I like your enthusiasm, but we don't have badges here so there is no reason to add tons of categories. Our List of Artifacts page could use some help cleaning up and adding sources if you want to make some edits. ƒelinoel 15:58, August 7, 2012 (UTC)
