As a DM, you've found one of the most useful sites, these boards. Here, at "What's a DM to Do?" you will find many experienced DMs with invaluable advice.
There are also many useful sites for on-line and downloadable DMing tools.
Once, not long ago, someone started a "Useful DM Links" thread and many people posted many useful links to that thread.
Some of the links below I found on my own, some I got from posts on that thread, and some from posters' sigs. All of them are on my "Favorites" list.
My thanks go out to Fixxxer, Dash Branaghan, PenderGrass, Unholydragoon, canamrock and the many others who have helped me out in the past and provided many of the links below.
I would also like to thank nekrolog, Vamagoss, DmLingSter, Farland, zarffyn, Kalidor, Domni Dalrose, Megadev, jgbrowning, KingOfChaos, ShogunWarrior, Kungfudude, Birched, Kexizzoc, Lottelita, Star Warrior X, Neonsamouri, Herithious, and goblin85 for posting links to this thread on the old boards. I apologize if I have forgotten anyone or mispelled anyone's name. :)
I hope other DMs find them as useful as I have.
