Tutorial: Reporting and dealing with vandals
Whether you're focusing on creating and maintaining content on Wikipedia, or expressly interested in patrolling recent changes, or even regardless of whether you're a new or experienced user, chances are good that at some point you will probably run across a vandal. This tutorial aims to give you the knowledge and tools to appropriately deal with this situation, when it arises. I highly recommend you skim over this, rather than reading everything at once.
