Sorry I lost all my bookmarks and can't find the Rich Diesel tutorial URL anywhere. Can someone give me it please?

Do a search on google next time.

Here's a bunch of tuts:

Richdiesal's tutorial, GREAT FOR BEGINNERS: http://richdiesal.jedioutcastmaps.com/tutorials/)
RD is wrong where he says JK2Radiant is better, get GTK Radiant, it is the same program, but GTK is for more games.

Claxon's for more advanced mappers: http://www.cydom.freeserve.co.uk/jk2web/)

Map Review, many many tutorials here for everything: http://www.map-review.com/index.php?page=tutorials)

Wedge's, good for more advanced mappers too: http://wso.williams.edu/~jshoer/hints.htm)

Bubba, yes I know this is for Q3, but JK3 and Q3 have the same engine: http://www.planetquake.com/bubba/tutorial.html)

lol. I searched Alta Vista for Rich Diesel, Rich Diesel JK2, Rich Diesel Jedi Outcast, and Rich diesel mapping and couldn't find the link.

Every now and then the page (hosted by pcgamemods) goes down. Unfortunately you might have to wait a period of time before it's back up again. If it's not up the next best thing is mapping forums..... ;)
