During the Silver/Bronze Age, the Justice League (of America, as they were called in those days) had a policy of rotating chairpersons. Hence, nearly all members of the Justice League, including the Flash/Barry Allen, served as team leader for some period of time.
After Wally West became the Flash, he also joined the Justice League, but during the JLI era and later during Grant Morrison's "New Big 7" era until the time of FINAL CRISIS, did Wally ever chair the Justice League? If he didn't, do you see it as a missed opportunity?
