The rules are now viewable online at www.4x4challenges.org.nz/webrules/, allowing you to view the rules without downloading the full PDF.
So if you need to quickly check a rule, and your hard copy has gone walkabout, that's the place to do it. Hopefully it'll prove to be a useful addition when the rules are being discussed in detail in the forum.
However, this new online version of the rules is not intended to replace the full PDF, and it's still recommended that you download and print off a hard copy for your reference.
Let us know if you have any ideas or gripes in relation to these new 'online rules'.
