well-connected
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).
