alt.greener.pastures was the newsgroup where Acton Lord and Action Lord tracked down the Pega.SYS, setting up the Bellerophon Gambit. Afterwards, Sig.Lad was marooned there, and spent months wandering the newsgroups before he met up with Constellation at the Gateway to Limbo.
Unsurprisingly, this is a newsgroup that does not exist in our world's version of Usenet. ...for now??
