I don't think there is any automatic notification of the Piggy Swap. It's all word of mouth plus the repeat offenders know to start checking Ella's (Starlight's) Seed Trading forum and cottage gardening forum sometime in October to see when the official start date will be for that year.
I usually post a note here in ATP's Classifieds and Group Buys forum, but this year Patti beat me to it.
