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.
