Secondly, Samurai and Martial Artist tags are alreay up and running.
Third: There is no need for a main character tag as whether a character is main, secondary or minor is already listed in bracket by the side of each anime in which they star. Also there isn't too much of a need for a sister tag. That sort of thing goes in the description.
Finally: This thread is about discussing the definitions of existing tags that may need to be further clarified for ease of use. If you would like to suggest tags, then please see this thread:
