I've seen the same questions over and over and over and over and over and over...

I type 'devmap <mymap>' but it doesn't work!
-Are you certain you have a bsp file?
-Is it in gamedata/base/maps?
-Did you set 'sv_pure' to '0'?
-Did you remember NOT to type 'mymap.bsp', and just 'mymap'?
-Was it compiled with sof2map, and NOT q3map?

How do I release it?
You will need the following things in your pk3:
/maps/mymap.bsp
/levelshots/mymap.jpg (or tga)
/botroutes/mymap.wnt (for bot support)
/scripts/mymap.arena (Tells the game what kind of map it is - look in an already released map for details)
/textures/mymap/textures (for textures)
/shaders/ (for shaders)
/models/mymap/models (for models)

I can't find the map models
-You have to extract them from asset0.pk3 into your base folder

How do I make the death pits?
Make a large brush filling up your pit.
Texture it with system/trigger
Right click on it, and make it a trigger_hurt
Press n
Set 'dmg' to '-1'.

How do I put music in my level?
Make sure you have nothing selected.
Press n; move the top part of the box down to 'worldspawn'.
Add a 'music' key with a value of 'path to music'

How do I add colored lights?
With a light entity selected, press k.

I still don't get how do add music.

Follow the directions.

To make a fire brush (torch) try the following (Using JKRadiant):

Create a FX_RUNNER entity where you want it to go.

Bring up the properties of the entity by pressing N

Enter a key of fxFile with a value of effects/env/small_fire.efx


(Maybe a MOD can make this a sticky thread???)

For a good selection of tutorials on how to make maps go here: www.planetquake.com/qworkshop3

Still one of the best resources for understanding
Radiant is the manual http://www.qeradiant.com/manual/Q3Rad_Manual/index.htm

OK, so if these are vastly reiterated FAQs..... lets write a huge tutorial/FAQ type thing. I suggested this over at jediknightii.net and they just called me a noob.....
Anyway, I came up with a page with some stuff I know about editing the game (www.imperial-center.co.uk/jk2.htm). Why don't we all come up with some quick tutorials SPECIFICALLY for JK2? Then when you see those questions again you can say, here, have a link to the guide.
Cmon guys this community was always fairly helpful towards people starting out.
