Unless you can read Japanese or German, there is none (and the Japanese one is massively out of date). All there are in English are online tutorials, a spec, and some mailing lists.

That's the real problem with D: great language, but it's so bleeding edge that the surrounding ecosystem is still small.

The best I can suggest is:
Summary: http://en.wikipedia.org/wiki/D_programming_language
Tutorials: http://www.dsource.org/projects/tutorials
General: http://www.digitalmars.com/d/index.html
Lists: http://lists.puremagic.com/
IRC: #d@irc.freenode.org

It's definitely not for the inexperienced or anyone adverse to constant change.
