Uncle Figgy's Guide to Gamemastering

[Dracos]

Okay, been reading through this lately.  The article is recommended primarily for GM's with at least a little experience, necessary to truly understand some of the stuff he's bringing up.  It's not the be-all, end-all of GM'ing but is definitely a good read well worth your time for an aspiring GM.
