In the GM's section - something I would like to see is a guide on how to make encounters both challenging and entertaining.
Specifically, how about some tips/guides on gauging your PC's parties strength and coming up with the right balance of creatures/NPC's that could (but probably shouldn't) defeat them?
I think it is difficult (especially for a new GM) to determine how many zombies or orcs or trolls to throw at your PC's. How would a new GM know to have the PC's run into 3 guards or 30 guards? And what level should those guards be so they don't kill the PC's in 4 seconds or allow all 30 to be wiped out without any effort?
I realize there is a skill to "adjusting things on the fly" as well, but again a new GM would need some tips on that as well.
Personally, I'm coming at this from someone who used to play but hasn't played in years - so I have some "sympathy" for someone new to RPG's that perhaps needs assistance that a veteran GM does not.
