Forum:How to report a user?

There's a user I'd like to report for abuse of the wiki's policies. I just want to know if there's a specific process to do so or if I can just post their username and my reasons why I'm reporting them. I don't want to say anything here in case I'm not supposed to. Thanks in advance. Lappyzard (talk • contribs) 14:53, December 30, 2010 (UTC)
