Anybody out there got a good UDM4 tutorial? I'm interested in learning it and I would like input on a tutorial site before I take it. So anybody have a suggestion of a quality tutorial. I don't want you to just randomely google for it. I want something you guys tried and thought was a very thorough tutorial on it. Also what should we know before we start UDM? I know CSS, HTML, and XHTML. So +rep for any help.
