sig block

[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}.
