:well-connected: adj. Said of a computer installation, asserts
that it has reliable email links with the network and/or that
it relays a large fraction of available {USENET} newsgroups.
`Well-known' can be almost synonymous, but also implies that the
site's name is familiar to many (due perhaps to an archive service
or active USENET users).
