The tag alias #56756 xeno -> alien has been rejected.
Reason: The word "Xeno" is itself typically a prefix to another word.
xeno is used in the same way as alien, which is redundant.
xeno is also the first four letters for xenomorph; new taggers may confuse the two.
EDIT: The tag alias xeno -> alien (forum #328924) has been rejected by @bitWolfy.
