sig block

/sig blok/ , n. [Internet and Usenet; often written. sig there] Short for
signature , used specifically to refer to the electronic signature block
that most Unix mail- and news-posting software will automagically append to
outgoing mail and news. The composition of one's sig can be quite an art
form, including an ASCII logo, one's choice of witty sayings (see sig quote
, fool file ), or even source code for small programs about which the author
wishes to make a statement; but many consider large sigs a waste of
bandwidth , and it has been observed that the size of one's sig block is
usually inversely proportional to one's longevity and level of prestige on
the net. See also doubled sig , McQuary limit.
