I’ve always found that personal recommendations are the best way to learn about new (to me) sites, and that goes for gaming and GMing links, too. And I think it’s a very safe bet that the TT community can learn about some great links from fellow readers.

So how about it — what GMing and RPG-related sites are in your regular rotation?

Anything is fair game: Ongoing sites, one-offs that only offered one awesome resource, forums, blogs, game- and campaign-specific sites — the works.
