Tutorials and help
I owe all these sites a big thank you for allowing me to learn what I know about JK2 mapping

RichDiesal's JK2Radient Mapsource - Mapping University
The core tutorials for anyone wanting to learn how to use JK2Radient, go from the basics to some complex stuff, and are extremely well explained

Bubba's Arena Mapping
These tutorials are for Quake 3, but as this uses a slightly different version of the same editor (Radient) almost all the tutorials still aplly, and they are very clearly set out, well explained and varied

JK2Mapping -
Has a massive selection of downloadable tutorials which cover all sorts of useful specifics about JK2 eiditing, including some very useful stuff on scripting things from patrol routes to altering NPC weapons/statistics.
