n/t is Internet BBS shorthand
for "no text." One puts it in at the end of a subject field
to indicate that there is no information
within the body of the post, and only within the subject. Frequently used on BBS's where most information is just one-liners in the subject
. n/t is the semantic opposite of r/o
. Some people use EOM
(end of message) instead of n/t.
Example: You're dumb! (n/t)
