If you own a Nikon D40, Nikon D40X or a Nikon D60 (one of the best-selling entry-level digital SLR cameras), it may be useful to stop by the D40/x/D60 Club Wiki.
What makes you quickly enthused with it, is the Wiki origin of this unusual kind of FAQ (Frequently Asked Questions). It is build by its users. From that you can infer that the contents are user-friendly. Technical information about the Nikon cameras (“Is Vibration Reduction (VR) Important?“) is neighbouring pure photo advice (“Tips for Manual Focus Shooting“)
