Scott and his team are a bit overworked so I wrote a simple scraper that turns your "games played" page on BGG into an Atom feed. If/when Scott gets around to officially supporting this, I'll make my feed generator redirect to the "real" one. (Atom is essentially the same as RSS and most services that support RSS support Atom)
Games Played Atom Feed Generator
For example, my games played.
I'm planning to also add feeds for plays of a particular game, or even a particular game by a particular person.
