I agree that Pre-Rumours is perhaps slightly irritating in its bias towards one particular band lineup, with everything else being discussed relative to that. The Early Years would suit me fine, too.
Although I'd get more of a kick out of changing the "Rumours" forum name to "Post-Mystery to Me" personally.
ETA: D'oh! I suppose you should make that Post-Heroes are Hard to Find. Although I prefer to forget that particular album.
