Editing NSB Eras

== Nostalgia Simulation Baseball Eras ==

For ease of reference and for purposes of organizing drafts, all players in our system are grouped into eras (not to be confused with ERA, the pitcher's earned run average). Older eras are composed of larger spans of MLB seasons than newer eras. This is because we try to keep approximately the same number of players in each era. The oldest eras (1871-1919 or "dead ball") are often reserved for Auxiliary Rosters.  The newest era is often reserved for new members entering existing leagues who, for a limited time (if the league configuration allows it) have exclusive access to the most modern players. Here's a breakdown of our historic eras:

#   1871 - 1892  
#   1893 - 1909
#   1910 - 1919
#   1920 - 1927
#   1928 - 1935
#   1936 - 1942
#   1943 - 1949
#   1950 - 1959
#   1960 - 1967
#   1968 - 1974
#   1975 - 1980
#   1981 - 1986
#   1987 - 1992
