Hi, welcome to Harry Potter Wiki! Thanks for your edit to the User:Magical1 page.
Hi, Magical 1. I deleted [[Template:Slythrin infobox]], which you created, as we already have an infobox for Slytherin characters and users. If you want to put this infobox on your userpage, it is called Template:Slytherin individual infobox, and you can find an explanation of how to use it on the page I've linked. ★ Starstuff (Owl me!) 18:23, 31 May 2009 (UTC)
