I've added notes next to the minis that were included because they were "Approved for use with..." one of the RPGA Eberron campaigns. Deadsmurf, I decide not to split them into a separate section of the list, because some of them are clearly Eberron minis and "Approved for use with...", and rather than list those twice, it seemed sensible to just add notes to the existing list. I hope it is a little clearer now.
I also removed a few minis that just didn't seem sufficientlly Eberrony, but there weren't many of those. Most of the dubious ones (including, rather strangely, the Cleric of Syreth) stayed on the list, because they were flagged on the stat cards as suitable for the RPGA campaigns.
