Can't Say that I do. Or should I say Have'nt yet?
In my gaming group FR has been the principal setting since I began playing DnD. It's been a great setting to play. And my DM has always been able to pull content from a myriad of sources.
I myself have no intention of putting Eberron content in my game. But I do enjoy reading about it and hope to catch some toasty tidbits to slip into my Campaign.
