I've also decided to count the number of times when Archer put himself in needless danger by going on a dangerous away mission rather than delegating to his capable crew.
well you could replace archer with kirk/
as for the alien thing.
look major aliens like the andorians and tellarites beyond a couple of verbal mentions almost totally disappear after tos.
and considering enterprise is more neae space then the later series it isnt suprising a lot of races later on were not mentioned.
there were numerous races in the federation by the time of tos that we never did learn their name.
